Kittens are so much fun. They can be just crazy, but they will settle down. Just remember it will take a little while. Here are a couple of tips from a seasoned cat owner and cat foster mom -
1. Get one of those cardboard scratching pad things. They aren't too expensive and it will save your furniture. Remember, declawing is inhumane. Many cats with behavior issues are declawed.
2. Feed him a good quality food. Your local pet food store can help with this. Male cats can get the crystals in their bladder from the cheap cat food. It's very painful and costly. They also poop less with the high quality food - there isn't as much grain in it.
3. Give him a tiny bit of canned food every day. It's good for their kidneys. I have been told to even put a little water on it so they get even more liquids. The shelter I foster for says that cats don't get near enough liquids.
Good luck - post pictures!!!
