We have a beautiful 2 yr old female Tonkinese cat that we rescued as a kitten. I have had several cats in my life but this one exhibits a behavior that I have never seen before. Whenever she is around food , be it people food, the dog's food or even her own food she circles the dish and scratches around it like she is in her litter pan. It is like she is trying to bury it or something. This weird scratching usually only lasts for a couple minutes or so but sometimes as long as 10 minutes. She also does this sometimes around the water bowl too. I volunteer at a local no kill shelter with 96 cats and have seen some strange behaviors but never this scratching thing. Does anyone else have a cat that does this ? Why do they do this ?
