I've run into this cat three times now in the same area. All three times have been when walking the mindees to and from playschool. I noticed her because she was missing a lot of hair on her neck and had a few crusting-over wounds. The first time I was a bit worried and wanted to take her to the vet, but obviously couldn't with two small children and a buggy in tow. I knocked on the door of the house she was skulking around but no-one was in.
She seems friendly enough, I've seen her again today and her neck seems to be healing, but she was eating something off the ground that I think was a mouse (it was dark, couldn't tell) and she has no collar so still unsure of whether she's a stray or not. No collar but looks to be in good health aside from the neck problem.
AIBU to try and catch her for a vet visit? If I see her again. There never seems to be anyone in the house she skulks around.
