We have/had two cats.
O Samurai-san, a small black and white male we got from the local shelter, was an indoor/outdoor cat (meaning he was indoors until the weather warmed up then he was outdoors). He was scruffy, a careless groomer and yep ...a killer. He died at age fifteen from a stomach tumor.
Mi-ke (Japanese for calico), was adopted from the IAMS cat colony in Iowa. She is completely an indoor cat (by choice)and, other than being entertained by a mouse, wouldn’t have the foggiest idea what to do with it or that it was a food item. Other than vanilla ice cream, has no interest in human food. She is nineteen and has high blood pressure. (Yeah, I know... “how can a cat have high blood pressure?” Well, she does.) She is also now blind, so she gets around mostly by memory and bumping along using her whiskers to detect obstacles. We try to maintain a consistent arrangement of the furniture to aid her navigation and, lately, we have begun to close off areas of rooms she might get stuck in because she can no longer see how to get herself out of a confined space she wanders into. She is such a polite cat that she won’t call out for assistance but will just stay trapped there until rescued.
