Welcome to Pet Talk, Elika!

Thanks for giving little Marley a home!

But better take her to the vet to make sure she's healthy, especially since you got one cat already!

Koko probably needs some time. One year ago I was worrying about the same things when I brought Lily home, but within a couple of days, she and Luna were best friends! Just let the cats work it out on their own and interfere only if somebody is really about to get hurt! But most likely this won't even happen.

And yes, please post some photos of Marley and Koko if possible!
