Ok. The weather here has finally gotten pretty bad at least for us. Neighbor has an "outside cat" adult neutered male who spends a lot of time on my porch. I thought he was a stray at first and started feeding him. I still feed him and socialize with him when I put the dog out. I even offer him the chance to come in and visit Clyde which he has never done. Wind chill of -22 and he decided to accept the offer. Boots went right up on the back of the couch and curled up and went to sleep. So far there have been no fights. Old dog is terrified and of course Clyde Is like "What?". Boots even asked to go out and he came back and tapped on the door. Clyde had a housemate when he lived with my daughter and there was never a problem between them. Not being a veteran cat owner I am not sure what to expect . One burning question of course is will they share a litter box? I have a spray bottle of water in case of fights. I am in a mechanized wheel chair so I have to keep the upper hand. Any advice would be appreciated. Dropped out of site after brief introduction because mom in hospital in another state and I have not felt well. Promise to post pictures once I figure out how to use the camera kids gave me for Christmas.
