Last summer a cat was hanging around, driving my indoor cats crazy. My older cat would get so worked up he would attack the younger cat. In the fall I saw the cat about six blocks away, along the highway. A few days later I saw him or her back in my yard. Because it was getting cold, because I didn't want him hanging around the highway and getting flattened, and because I'm a crazy person, I started feeding him. We live in a tiny house on a tiny lot but I put food in the pine trees at the back of the yard. Now he is waiting for me when I come home from work. He sits in the yard and meows very loudly. This is annoying and will cause problems, especially when it is warm enough to open the windows. He is very nervous but his hunger trumps his fear and he will follow me and will come right up to me when I put food out. He will even eat out of my hand but he is so nervous I don't try to pet him. There is another cat that I see sometimes that could be his twin. I don't know if the other cat is a stray or somebody's pet. And now there is a third cat, a big fat tabby cat that could be somebody's pet or a recent stray. I care about all of them but I don't want a cat colony in my yard. Any suggestions would be appreciated.
