he is 2.5 month old. I know he is very young. I adopted him month ago. I have another kitten around 3 month old. He is also adopted 2 months ago. They are like best friends now. Big kitty is perfect, loving, caring not aggressive. But small one is cries espeacially at night, he wants to suck my shirt at night. He is not alone, they play all the time, sleeps together. Vet checked him and everything is fine. Do you think he changes when he grows up? I am sleepless for a month now.
