I still can't believe how many cats you have. That in itself has to be a full time job! It is to hard to have one where we live especially with a doggie door, not that we don't want one. They are too many coyotes, feral cats (at least 50), and bad neighbor dogs to even try, Since our last one had to be put down. The neighbors dog got it and broke its leg and by the time I rushed to the vet (2 hours) away, it was in shock and would not have survived the surgery. It was so tramatic that we haven't even tried again. I threaten to kill the feral cats around here if the eat any more chickens but 3 years later and they are all still alive. My husband did try once and I made alot of noise so it would run of before he could shoot it. We really do like cats..I just don't like them eating my seramas for lunch!!! I need to catch them all and get them spayed and nuetered, but that would be at least $5,000.
