I am trying to have Oreo and Inkspot to like each other.

I am trying to have Oreo and Inkspot to like each other. They are sisters and when I got them, they liked each other and Inkspot was away from Oreo for about 3 or 4 month and now they don't remerber each other, but I think Inkspot do and could not tell her.:confused: :( :( :( :confused:

Sibling rivaly is common among littermates. I do not think you can MAKE them like each other. They will decide that on their own.

Welcome to Pet Talk :D

Did you introduce them slowly this time ?

If not, it might be worth seperating the cats and trying a very slow introduction.
