I think the whole thing is a troll. Note the lack of fold lines on the note.

Newest site from the Cheezburger network! “Notes on Cats”!

If she didn't want anyone putting notes on her cat, she shouldn't let her cat outside. Considering all the bad things that could happen to a cat outside, she shouldn't be worried about someone leaving a friendly note. Also… she comes across as very bitchy, when the person was just trying to pay a compliment.

Sarah? What is her cat, a receptionist? No wonder her cat left in the first place, it went looking for a better name.

are we to understand the owner replied with a note on the cat?

Plz don't abbreviate “please.”

My dad was telling me a story about how he went outside and he noticed that Batman was up in a tree and the dogs were barking at him. Apparently he had gotten a cat and named him Batman because he looked like Batman. He failed to share this detail prior to the conversation.

At least her name wasn't “Burger and Fries”. NO ONE could stick a note on Burger and Fries! Not even Chuck Norris could do that.

I actually used to have a cat named Batty because he had big overgrown ears like a bat, or Batty Coda from Fern Gully.

Unless you staple it on, please feel free to put as many complimentary notes on my cat as you like.
Also: Sarah is a stupid fucking name for a cat.

sarah's/batcat's owner is a rude fucking bitch. this person is paying her cat a compliment. least she could do is say “thank you” before chastising the poor guy.

hahaha I really wanna put a note on a cat now.

I'm agree! BatCat is much better XD!
