This is the second time in a year that I've taken in this cat without ID. The first time I sent her off with a collar that said "please tag me or someone else will". She disappeared for a few weeks but then returned last week to hang around in the parking lot behind our building, missing my collar, looking quite scrawny and wanting food.
Perhaps she has a home but is always taking her collar off. Will hang on to her for another week for the owner. If no one claims her it's off to the vet for a checkup and spaying. Then perhaps she can live with me and lounge on the new Tirup chair anytime she likes.
