Quick question...is this normal cat behavior?

Actually it is both. I have raised lots and I mean LOTS of mèo con bởi bottle and all, like, 50 of them have turned out little monsters. Kitty monsters happen when people don't correct mèo con for doing things wrong. Anyway, mèo are naturally nocturnal mammals so if they are active at night it is no problem.

Remember mèo are nocturnalso they are active at night. Most mèo con are crazy anyways they are just like little kids. They will play with anything that di chuyển hoặc is curious to them. I have older mèo and they still play with my feet!!!

mèo FOREVER!!!!!! :3

The cat is just being a kitten. Its normal kitty behavior to attack anything that moves (feet are often a casualty of this) however, this should not be allowed hoặc else you'll have a full grown cat attacking bạn wherever your walking. I good way to stop this behavior are tether toys (like in the picture) bạn can control the toy and at the same time the cat gets to attack something he thinks is moving and alive. They will eventually learn to go after the tether instead of peoples feet, hands, ect.

Also its very normal for cat to bring bạn "gifts" like your sponge he puts in your bed. Its an instinctual behavior that mèo have to teach their mèo con how to hunt and bring back food. He is essentially saying "your not a very good hunter, so I'm trying to teach bạn bởi bringing things I found to you" this is an often funny behavior in my house because my cat Daisy, loves to bring me my own flip flops. Usually one bởi one she'll bring them to me hoặc hide a few and I always find them with little puncture wounds (lol) it got less hilarious when she caught a chuột she had been stalking underneath the stove, and brought it to me ALIVE!!! with the tail hanging out of her mouth. She dropped it in my bedroom and it began to run around the room while I was screaming in terror, and she was chasing it.

mèo are colorful animals.

It depends on how bạn raised it, but also, different mèo have different personalities. Maybe she just loves to play and has too much energy. And no, she's not possessed. lol
