I knew 2 people who had outside and inside cats. Both were kind of like the Statue of Liberty.
Give me your poor, down trodden....
My grandma had a few outside cats, and she would feed them sweetened condensed milk. She had 2 inside cats too (Charlie and Nasty). When I visited, sometimes we would go to Arthur Treachers to eat. You know before we left we had to bring back at least 2 filets for the cats!
I knew a 1st grade teacher who also had indoor and outside cats. She had about 10 indoor cats and a dog. Her Mom had the upstairs of the house, and she and her husband lived downstairs. Cats seemed to be everywhere. I had to take a dose of Allergy medicine everytime I visited. Of course they all loved me! She would clean out one bedroom and shut the door so there would be 1 cat hair free space in the house for me to stay over.
