Magnificent. I hope you always add more cat variety to this addon Mr.Dev.
Would also be cool if the addon had different modes of operation, like: Show only black cats, only white cats, etc.
Another interesting ability you could add is to make it show cats on other sites, too. Not just on youtube.
Maybe even animated cats that walk on pages and do funny shit. Make it all optional tho.
Think big Mr.Dev. ^^)v
