you have a pet or more?

I kind of find my experiences with my pets these last four years to be puzzling. About 4 years ago, we had two dogs. A spitz and a chow-chow. Although they are both dogs and the chow-chow is a very friendly dog, the spitz always attacked the chow-chow upon sight. Of course, the chow-chow (despite its reluctance to pick a fight) always prevails because of its size and strength. Lately, just last December, 2006, we acquired a half breed terrier and an alley cat into the house. We were expecting they'll never go along together. Much to our pleasant surprise, they come out to be quite good together. They play, eat and sleep together. Not at all times though, but this takes place everyday.
