I realize how frustrating this can be so, Diogenes and Harmonious, I made you a cookie … but I eated it.
B-but it’s ironical, see? And it’s kitties!
No offense, I think it’s pretty stupid too…
Unfortunately I also find it’s funny. Woe is me.
It’s a kind of pseudo-baby talk (projected on cats, for some reason), which I guess was supposed to be cute or amusing, but of course it isn’t either. Baby talk is pointless. If the baby can’t understand regular language, what makes people think s/he will understand gibberish? Many people talk to their pets in baby talk, which, of course, is even more pointless. (C.f. Gary Larson cartoon where the pet owner’s balloon has a normal language chastisement, and the pet’s balloon has verbal static.)
All of this, and that some people have turned it into a programing language, just goes to show that they must have too much time on their hands.
BTW: “I can has…” is a linguistic construction that no English learner would ever produce, no matter how young.
Wasn’t there a thread where bigbabysweets2000 has a picture of a sign he made where the word “bitches” is spelled “biitckes” or something like that? I think the lolcats might be his spirit animals. 
I suk at spelling already. Happy?
Diogenes the Cynic and Harmonious Discord, you are my heros.
I started the pit thread, but this one has stirred more righteous indignation, just as it should be.
Please, make them stop… it hurts ears/eyes.
And anyways, it doesn’t make sense. All cats have perfect grammar.
Okay, despite my use of a lolcat-ism upthread, the grammarian in me does want to rebel when I see those phrases but the cat lover in me just wants to laugh. I agree that it should be taken in small doses and there are a few too many “I can has …” threads here.
But, frankly, I am more annoyed by all the “Ask the _____” threads. Oh, and that thread in Cafe Society where someone is ranting about an actor and he can’t even get his frickin’ name right and I have to keep seeing it every time I go into that forum, plus several other people in the thread keep getting other actors names wrong because they can’t even check their facts first!!! hyperventilates Dangit, now I’m more annoyed and I need something to amuse me. wanders off to look at lolcats
Learning English as a first language, yes. However, it might just be possible that a cat might have made a stab at picking up some of the words but not the spelling or grammar and thus produce a motley pidgin of almost-English in an attempt to communicate with a more primitive species. The result is Engrish-like and quite amusing, if silly/stupid (your pick).
There. Now I’ve gone and killed the joke. Happy cat has run out of happy. 
If that kind of grammar goes unchecked, u wanna wash out.
I find it to be a harmless bit of whimsy, myself. And the cats are cute. (What can I say, I’m a sucker for cute cats.)
My favorite lolcat has proper grammar, actually.

Maybe. I wouldn’t know, because my cat speaks Latin, and quite well at that. Doesn’t bother with English.
And he’d be appalled if I took a picture of him on put it on the Internet.
Apparently, Elder Gods can’t spell, either. 
*Edit: Whoops, wrong code.
Hear hear.
Pretty good Time article on the phenomenon linked from that blog. My bold.
That is nine kinds of funny! Iä baby, iä!
Only part of the time:
Geez, I know Lolcats aren’t for everyone but some of you people sound so humourless and angry over this stuff. It’s not like the lolcats are trying to put creationist stickers in your kids’ science books or something. Everyone just calm down.
