So right, Ken. My next cat will be an 'indoor' cat too. But this one was a feral cat that adopted us, and she stoutly refuses to use a litter box, so the yard is her kingdom. Happily it is fully fenced to 6ft. so other than the raccoons she has no predators to deal with, and she is 15 so has done well for an outdoor cat. Except for the toasted coconut.
