Most animals are not thrilled about a new friend in their house initially - there is jealousy & concern that they won't be top dog anymore, but with time they adjust - sometimes in just days. I love having 2 - they are great company for each other when you are gone. The can play together & cuddle together. My male Siamese died and now I think I may be ready for another one - in part because my female seems so lonely, she only knew life with him.
Two can be great friends |
