I have a feral female at least 13 years old that pooped in her basked on the porch last night for the very first time. I saw her sleeping in it when I closed the door to go to bed. The poop was in the basket on the towel in the morning. I've been feeding her for 12 years. Obviously we've left before for vacation and have had petsitters always come to feed her at regular times. The night before we had been away for only one night and a neighbor came and fed her and told me she ate very well. I'm going to take the sample to the vet for testing, but it looks perfectly normal to me. Any ideas why she would have suddenly done this? I'm wondering if she could be getting feline dementia.
