Is this normal of a kitten? I ask because I have had 4 kittens, and they were always so playful it was almost annoying lol..so this just strikes me as odd? I know kitties sleep a lot but I mean, to never to play ever? He seems happy and is eating, using litter just fine, he just wants to cuddle and sleep all day and all night. I feel like this seems really abnormal for a kitten his age, was wondering your opinions?
