does my avatar look like a cat? Or one that has had a surprise?

Your avatar looks like a cat on drugs. Seriously, it's all wide-eyed.

Yes, a cat who has just had a very nice surprise. Not a food or a thing surprise, more like a friend has just come in unexpectedly, maybe her owner, and the cat is happy and saying, "hello".

Yes, it looks like a surprised cat.

It looks like a cat begging for something (see how the pupils are round)

Looks like a wolf

Err...both.
