Someone just wrote into say that another cat of hers had gone missing from her home. This is the seventh cat to have gone missing in the last two years from her house. She had checked with the AVA - no traps were loaned out to anyone in her area. She wondered if the latest cat may have wandered off as it does not like one of her newly adopted cats.
I told her it might happen, but losing 7 cats in that time makes me suspect something else is going on. I asked if any of her neighbours might not be happy with her cats. She said she had spoken with them and they seemed alright with the cats.
Several things might be happening - the cats might have been eaten by a snake or even killed by another animal. Or someone may be trapping the cats but not telling the woman in question.
One way to tell if your neighbours might be having problems with cats is to look out for a fence like the one in this photo. It could mean that the neighbour has a dog and is trying to keep the dog from running out (as may be the case in this photo), or it could mean they are having problems with cats running into their garden. This is usually a good clue that someone isn't too fond of the cats running into their home.
As I advised the woman, since these are her home pets, the best thing to do is to keep them indoors. The area is unsafe for some reason and it's easier to keep the cats in than to find out why they are disappearing.
