question on intro-ing a new kitten

Well my son has started asking for another kitten-- PB is 4 months old now and is obstinate-- i dont have any extra rooms that I can close off if we get a new kitten as all our bedrooms are in use by familymembers, and the only other room with a door is the hall bathroom where PB eats and plays ( i dont have anywhere else that i could put his food plates either without our dogs getting to them. The laundry room i could close off but i would have to move PB's litter box out of there and into I dont know where, plus its a very very traveled room and there is a broken window in there that PB uses to get in and out when hubby tries to lock him out of the downstairs living room

-- do yall think PB will be ok since he is so young if we get a new kitten?

feedback please...

I would suggest using one of the bedrooms as the new kitten room. So much more cozy if he sleeps all night, maybe with your son? Just put food and litter in there for a few days, or as long as it takes for the introduction.

Maybe you could get a similar size kitten, so they are evenly matched for wrestling.
