Kitten sleeping a lot

Hello all!

I adopted a 5 month old kitten last Monday. He is picture perfect and all was well at his vet visit. He is eating like a horse, drinks water regularly, and is using his litter box wonderfully. However, the past few days he has been sleeping an awful lot. I'm thinking that it is possibly due to a growth spurt or due to the last of his adult teeth coming in. He will still play when he is awake. However, it seems as if he has gotten smarter during his play and plans his attack before chasing the toy. Do you think it is because he's growing, he's teething, or because he is calming down that he has started sleeping more?

Sincerely,
A concerned new kitty parent

Congratulations on your new kitty! 

It's possible a combination of things.  He could be settling in, but it could also be he's preparing for a growth spurt.  If you took him to the vet in the past couple of days and he had shots, it could be from that.  Keep an eye on him as it's very common for kitties in new environments to come down with an upper respiratory infection about a week to 10 days after coming home.
