Hi,

He should be on kitten food (it is in smaller chucks) until he is 12 months old. Try another brand if he dislikes the one he is on.

Is he attacking your daughter or playing ? Personally I would adopt another 9 week old kitten so the kittens will play with each other and not your daughters face !!!

Spraying water at the cat is the right punishment but I wouldn't lock him up to. Punishment has to come at the moment of nawteness or they don't get it. I would just stick to water.

Soft paws come in one size, people recommend that you ask the vet to apply first set and shows you the best way of doing it and you just glue the new claws on as the old ones drop off with age

Good Luck
