We live in an apartment and it was very hard to convince my husband to get a 2nd cat so getting a 3rd cat is out of the question. Besides, my daughter lives next door and she brings her cats over from time to time and they scare Sunny. In fact, when they come over he hides under the bed. I think because she was already 3 years old when I brought him home, he is used to her and not afraid of her but he is afraid of other cats.
