We lost our beloved cat recently and my husband surprised me with a new kitty. He’s 9 weeks old. He’s a great kitten, eats and poops fine, very playful. This is only his 3rd day at our place and we were introducing one room at a time to him. Today he got to the the whole house. Here is the thing— If he isn’t eating or playing/cuddling with one of us— he walks around meowing. If he doesn’t see any of us in the room, he’s quiet though, so I doubt that something hurts him. I had cats all my life, and never seen that happening. Is he just stressed and looks for his brothers/mom, or should he see a vet for that?
