I was just walking my Scottish Terrier, Haggis. We walked passed a betting office where I saw five seedy arabs sitting in front with a pitbull. The second I spotted it, the pitbull started running towards me and my dog. I had to react quickly so I picked up my dog while the pitbull was jumping up at me trying to kill Haggis. The owner was a complete idiot and yelled at me for kicking his dog. He finally got up and struggled a lot to get his pitbull away from me. Haggis luckily seemed unaffected by the experience.

>Boy, Anon. That's a startlingly large erection you got there. It's not for me again, is it?

I need help identifying the worlds most ugly creature.

Since I have to do it anyways, figured I'd share animals that cats kill.
These are all animals who are anywhere between endangered and extinct, with invasive F. catus being considered a major contributing factor. Only including species where domestic cats are mentioned by name, as either direct or indirect (spread of Toxo, FIV, etc).

What, if any, are the major roadblocks for domesticating a humminbird species? They breed fairly quickly and are already fairly docile to humans.

I know I'm overlooking something, but I'm curious if it would be possible to domesticate them into an actual household-worthy pet.

What kind of caterpillar is this ?

Hey /an/ why does my cat vibrate?
Not like purring, He literally vibrates and shivers in his sleep, its like watching a massage chair go off in the middle of the night, and he only does it when hes curled up trying to sleep.
