That cat is obviously injured and scared, not to mention cornered in a cage, I don't blame it for freaking out. Put yourself in the same scenario and you'd freak out too. I personally love cats, alot of people don't, but it's usually because they've had bad experiences with cat's that are somewhat wild. If you want your cat to be more personable and people friendly, instead of leaving their food bowl filled with food, feed them on a regular schedule 4-5 times a day. I do this with my cats and they learn to be around you and depend on you for their food. Everyone who meets my cats, even people I know that HATE cats, love mine. And feeding them a small amount, several times a day, on a schedule helps to keep them from getting too fat, which is a big problem for house cats. Oh yeah, no outside, it makes them more wild(mean).
