I love to take my cat over to my friend Rhonda's house. She has a cat the same age as my Sonsy...her wonderful baby, Pawley. And we love it when she brings Pawley over to visit my baby Sonsy. The cats run and play and hide and sniff and hiss. They are somewhat happy...but they are grumpy a lot of the time. But my friend and I love it and enjoy it so much. Question is...is it better (for them) to leave them in comfort (and loneliness) in their own homes or to take them to their friends' homes and have them be uncomfortable but stimulated?
