I've never had an indoor cat, but I've had a few barn cats that were like family.
The last cat I had was a yellow tiger (not quite a Morris) he wandered up to me on a frozen February morning while I was doing chores outside. He was about the size of my fist. I decided to keep him, but we didn't have any chow for him so, I brok3 a piece of white bread in a bowl and pour half a can of condensed milk over it. He wolfed that down. In the evening I had prepared a box with an old blanket for him, picked up his bowl and went inside and repeated breakfast. He was mine at that point. In the afternoon, I drove into town and bought him some Kitten Chow. As I drove up the road I saw his siblings every 4 or 5 hundred yards Thrown out the car window at high speed, nobody else survived! The only reason he survived was we live a short distance from the traffic stop. For the rest of his 14 year life he had a scar on his right cheek and his front left paw was crippled. A few nights later, it was going to be -20 F, I ask my mother-in-law if she would keep him in the garage for a few days. She very grudgingly agreed. BY the second day she had named him Toby, and by the third night she had him indoor and litter box trained! My mother-in-law developed Alsheimer's and Toby was her constant companion until she forgot how to live. He went with my sister-in-law and lasted another 5 years, the he forgot to wake up one day.
I think back to the six kittens in the road and how they too would have been fantastic companions that many people truely need. Such a waste!
