A note from Michael:
My cat was so proud of her achievement that I didn't have the heart to undo her work immediately. I'll leave CatBlock in place for a few days, during which you can enable or disable it on the AdBlock toolbar button → Options page. Dancing photo credits here.
By the way: I quit my job to work on AdBlock for Chrome and Safari full time (when the cat hasn't locked me out of the laptop). Every cat you see in CatBlock is an ad that I've been silently blocking for you. So I agree with her that you should pay some money to help me keep AdBlock going! I promise I'll send you a thank you note (or more, depending on how much you pay.)
And also, you should share this using the buttons below, and follow me. 98% of Chrome & Safari users don't have AdBlock installed, so you'll be a hero for spreading the word!
Update:
Wow, um, there's a lot more demand than I expected for CatBlock to not disappear. So how about this: vote with your dollars. I've made a standalone version of CatBlock, and will send it to you if you will support AdBlock with a monthly payment. Long live CatBlock!

You've made this the happiest day of my lifee.
ReplyDeleteTHIS IS SO FREAKING AWESOME. PLEASE KEEP THIS UP. I LOVE YOU AND YOUR CAT. Thanks for this genius concept! (Except now I miss my cats since I'm away from home right now...)
ReplyDeleteSuddenly: CATS EVERYWHERE.
ReplyDeleteI like cats, and I don't like ads, purrrfect
ReplyDeleteHa ha, good one. I just manage a Lolcat website and I was like, how are they here from the website?

DeleteCatBlock forever! CatBlock for president!
DeleteMy apologies, I never really felt like paying for adblock before, despite its usefulness. I saw Catblock and I thought "I have to send some money through the internets for that!"
ReplyDeleteI never have had so much fun looking at ads:D
ReplyDeleteA lot of thanX catBlock. U are my hero and inspiration..
ReplyDeleteu kittyz so genius!

ReplyDeleteYou sir, are great and one of the best persons in this freaking world. THANK YOU
ReplyDeleteThis is lovely. Made my day. If you make CatBlock permanent, make it have a feature where I can choose my own photos from a folder to appear instead of ads, too... I'll definitely sub, if the price is reasonable. That would be beyond epic.
ReplyDeleteYour cat is a genius. My cats are now 100% more happy using the computer thingy now that CatBlock has been installed. My cats are now very happy that I have donated money, but are pressuring me to spread the litter, oops I mean spread the word about CatBlock. I will bow to their pressure, even tho I think this is a very secret ploy to take over teh internets.
ReplyDeleteAll hail CatBlock
Rly kuul idea thiz iz! :D >^..^<
ReplyDeleteI wondered what was happening. Then I realised it was awesome, meaning to support AB for a while, now definitely will try and find the cash!

ReplyDeleteI thought the internet had gone cat-mad.
ReplyDeleteExcellent modification! I hope you get more people (like me, for example) to pony up some money for this excellent service.
You have made my year. This is probably the most fantastic improvement you could have made.
ReplyDeleteI like cats. Good work! Funny. And I can use it in the Safari and Chome. This is THE BEST APPLICATION for my MacBook Pro and MacBook Air.
ReplyDeleteToo bad I'm still broke... would have loved a pretty song of yours on me.. :(
ReplyDeleteAnyway, this is a pretty epic campaign!
ZE KATZ WYL RULZ WURLZD ONE DHAY!

ReplyDeleteDonated.
btw, I will support you to keep CatBlock going on :D
ReplyDeletePlease....let the cats rule the internet... plaseeeeee :D
ReplyDeleteIt maekz my cat so happy!
ReplyDeleteI wasn't planning on ever giving you money for this (sorry. I'm in high school and can't afford much). Then there were cats. I had to give money when my ads were replaced with cats. Take my money, good sir.
ReplyDeleteCatsplosion!
ReplyDeletepaws down, best thing to have happened to chrome ever!
ReplyDeleteI want this enabled FOREVER, PLEASE!
ReplyDeleteYOU MUST KEEP CATBLOCK! MOST AMAZING IDEA EVER!
ReplyDeleteHaha. CatBlock, what's not to like!
ReplyDeleteOMG I LOVE YOU ADBLOCK. <3 <3 <3 <3 BEST EVER AHH <3 <3
ReplyDeleteVery inventive! Advertisement is a kind of violence. Please, leave CatBlock as an option in the future, not only our two cats will appreciate it. Add also FlowerBlock to "pretty pictures" (said my wife). And our "tiny" (180 pounds) english mastiff puppy Eddie would like to have the option to use PuppyBlock.
ReplyDeleteLmao hilarious!
ReplyDeleteLOVE THE CATBLOCK! Keep up the great works! Thanx!
ReplyDeleteYou made my day! Thx!
ReplyDeleteLmfao, what a surprising thing to wake up too.
ReplyDeleteI didn't realize how useful Adblock was until i saw 5 or 6 cats on each page blocking ads for me. In addition to making my day with cats, it made me appreciate how awesome Adblock really is :D
ReplyDeleteFaits in hoomaniti fully reztored :D
ReplyDeleteI just "suscribed" the monthly payment for CatBlock, any chance you would accept pictures of our cats to throw into the picture database so I occasionally get to see my kitty Aliera on the intertubes?
ReplyDeleteCatblock rulez! I lulzed soo much!
ReplyDeleteI LOVE YOU
ReplyDeleteUUUU MAKE MY DREAMS COME TRUE
Pure Awesomeness. I really like it better than the original. Please make it a permanent option to run adblock as catblock :)
ReplyDeleteI love it! Don't make the cats go away! They definitely brightened my day. <3
ReplyDeleteI was thinking to myself, the internet's cat ratio seems to have increased recently. And it haz.
ReplyDeleteLOVE IT! <3 Makes the world a much better place!
ReplyDeleteCatBlock FUREVVVRRRRR!
ReplyDeletePLEASE KEEP IT UP, I HAVE NEVER FELT SO TERRIFIED AND DELIGHTED TO SEE CATS STARING AT ME THROUGH MY MONITOR. <3 NEVER LET IT GO AWAY
ReplyDeleteTHIS IS THE MOST AMAZING UPDATE FOR ANY PROGRAM. EVER.
ReplyDeleteYou got me with Nyan Cat.
ReplyDeleteI luvz yor catblokz!!
ReplyDeletewe can haz catz!
ReplyDeleteyay. i luvz yor catblok!

ReplyDeleteI'll be very frank with you. I wasn't going to pay you a single penny. Then, I realized that all my ads turned into Cats. Now you have my money.
ReplyDelete>Just browsing Facebook...
ReplyDelete>A wild Cat appeared!
>I scroll down
>Suddenly: Cats all over my page
>Laugh hysterically
>Try to refresh the page 100 times
>CATS Y U GO AWAY
>Then i read this and laughed for about 10-15 minutes
Well that's my morning.
This was worth waking up at 3am with leg cramps to see. :)
ReplyDeleteWant to keeps! Lovz its!
ReplyDeleteI'm still drooling. Also, the dancing cats credits: priceless. You sir, are a winner!
ReplyDeleteI luvz it! I rarely lough when I read the news, but the more I'm scrolling, the more cats! Being owned by two cats, how can I not love it? ;) Now off to find the donate button!
ReplyDeleteThe cat pictures are great and the fact that they are instead of ads makes them all that more enjoyable.
ReplyDeleteFacebook suddenly full with cats :D
ReplyDeleteCatblock is Awesome! Please keep it around, pretty please? With fresh herring on top...
ReplyDeleteWhat a cool idea your cat had 8) Thanks
ReplyDeleteCAN WE KEEP THIS FOREVER *___*
ReplyDeleteAnd I sat here in England planning my holiday in San Francisco wondering why a shopping mall site had so many pictures of cats. Wonderful
ReplyDeleteAwesome! Made my morning! Please keep Catblock going - it makes the whole internet a hilarious joke to enjoy indefinitely.
ReplyDeleteWell done all around. My first time ever paying for freeware, and happy to do so.
ReplyDeleteI freaked out when I realized that AdBlocks was blocking the videos commercials too. You're a benefactor of mankind :) And the cats idea is hysterical.
Thanks again so much and keep up the hardwork :) Meeeoowwww
I can haz catblock forever?
ReplyDeleteAWSOMENESS!
WOOO! Cat's FTW! <33 =^.^=
ReplyDeleteMuch luvs to you sir.
ReplyDeleteWhat an inspired nudge towards the checkout. *donates for first time*
ReplyDeleteThis is the greatest thing to ever happen to the internet since its inception, I LOVE CATS and I HATE ADS - it is perfect. You are brilliant man!
ReplyDeleteTHIS IS AWESOME PLEASE MARRY ME (either the cat or the owner is fine)
ReplyDeleteLOL. This is funny. Cuteness overkill.
ReplyDeleteThis is so awesome I cried. Seriously.
ReplyDeletePlease let it be permanent.
this morning i kept seeing cats and was like wtf is going on lol this totally made my day. i love seeing cats everywhere instead of adverts <3
ReplyDeleteCooool! All your milk are belong to us!
ReplyDeletei cant stop laughing! this is so awesome :D
ReplyDeleteMy cats approve. That is not something that happens often.
ReplyDeleteI only realised there was a feline theme in the advertising after I had been on The Economist website for about 20 minutes. I got to the bottom of the page and the was a fat ginger tom. Hilarious, I'm telling everyone. Keep up the good work!
ReplyDeleteOk, although I'm not a fan of cat pictures, I have to admit that was one of the best ideas I've seen in a while! You have my money, sir! Keep up the work and don't let your cat use the laptop in the future ;-)
ReplyDeleteI thank you for making me smile/ laugh / and a bit sad cos of that hardworking cat :S:S
ReplyDeleteSuperb! Awesome cat work!!! Feline fever rules 4ever!!! Thank you!!!
ReplyDeleteThank you very very catz from the Netherlands!! I have a great day THANKS
ReplyDeleteYou made my whole family start the day laughing. Many thanks!
ReplyDeleteI am really convinced: I'll send money and perhaps some pics of my cats...he heee
ReplyDeleteAbsolutely brilliant idea. I love cats. You made my day... Many days ;-)
ReplyDeleteYou win. I've loved AdBlock for a long time, but never felt compelled to give money. But the cats won me over. And I actually see just how many ads you've been blocking all along! Great idea.
ReplyDeleteThis is great. When I saw a cat on the right side of youtube I was like what??? Then I saw it was from Adblock and I was like I WANT TO KEEP THIS!
ReplyDeleteFangks Mikulz cat, yor hansum!
ReplyDeleteSuddenly...
ReplyDeleteCats everywhere.
Thx, you made my day.
Fabulous idea! Thank you! Who wouldn't want to see cats instead of ads?
ReplyDeleteReally, really love the idea!!!
ReplyDeleteThanks
=^.^=
Best thing to happen in my life in a long time ..Thank-you n I think I love you ...<3
ReplyDeleteI really like the cats :D
ReplyDeleteI Will suport you. PLease continue with cats and other animals! Thank you!
ReplyDeleteorsom
ReplyDeletek thanx bi
Purrrfect! Your cat's a genius ;)
ReplyDeleteThis is awesome. Please don't remove them cats!
ReplyDeleteLove it!!!. When I realized all those beautiful cats came from AdBlock I couldn't stop laughing. Made my day. Love it!!!.
ReplyDeleteAll yourz bazez belong to uz! Miao!
ReplyDeleteI love cats! I love every kind of cat! I just wanna hug all them, but I can't hug every cat...cause I'm really allergic. This is a fun alternative :D
ReplyDeleteWhat a wonderful upgrade to browsing the interwebs.
ReplyDeletethis caught me by surprise and I am not a cat lover. Not hater either. You know what? it makes sense, replacing ads with pictures instead of empty spaces. you are a genius.
ReplyDeleteWill you marry me?
ReplyDeleteAwesome, made my day
ReplyDeleteLove love love the kitty ad block!!!!!
ReplyDeleteLOL! So awesome.
ReplyDeleteI can't tell you how many times I've laughed this morning, which is amazing considering I'm doing work at home on a Sunday morning. I actually signed up for monthly payments just so I can keep seeing the cats. The only request I have is that you don't just use pictures of cats with those stupid un-words on them. If you have to use pictures with words, at least pick some words that easily make sense. Guess I'm just not cool enough... Thanks for the laughs!!
ReplyDeleteThis made me laugh so much. Ok, ok, you certainly deserve a donation.
ReplyDeletei CAN HAS DIS PERMANENTLY PLZ? KTHNX
ReplyDeleteThis. Is. Amazing. Please please keep it this way! It makes me smile :)
ReplyDeleteThis has to be the most awesome update of anything, ever. You, sir, have just earned another $5/month!
ReplyDeleteI actually believed your real name is "Mikul", until I read the note more closely...
ReplyDeleteI want to keep the cats!!!! Can't stop "Awwwwwwwwww"ing at the pictures!
ReplyDeleteLove it, this is pretty creative...
ReplyDeleteSHUT UP AND TAKE MY MONEY!
ReplyDeleteSeriously, this is the best thing ever. I love the cat eyes staring through banner ad space...
Replace ads with cats? Purrfect! *pawhugs* 2 u & ur cat, u have given efurryone *happy internets* =^..^= xxxx. @karen_hackett
ReplyDeleteWhen I saw cats every where, I just realized how adblock helping me out so much!
ReplyDeleteI love you so much, and wish your happeness!!!
You have got to be one of the most awesome developers ever! Is there a way, maybe possibly, in the future you can make CAtBlock a real thing?? LOL- that would be freaking amazing. I'd pay for that!
ReplyDeleteGreat idea! I'll send my contribution in money, and perhaps some pics of my cats too..:-))
ReplyDeleteAwsum. There's no better word to describe it. Great stuff Mikulz! God I love the Nyan Cat music!
ReplyDeleteSuddenly AdBlock completes me
ReplyDeleteOh my gosh. This is amazing. I absolutely love it. Please Please Please don't get rid of it!
ReplyDeleteLove meows! You madez mai day!
ReplyDeleteHeck yeah I'll donate for Cat-Block. I love teh kittehs so this is awesome!
ReplyDeleteBest thing on the internet. I think I will pay for a extension for the first time in my life

ReplyDelete
