Old neutered black and white male cat found Pentwyn area

We took this old cat in yesterday from the Pentwyn area. We have called him Fred. He was found as a stray. He needed a dental as his mouth was in a bit of a state which The Cardiff Cat Clinic carried out along with a health check. He is a old boy but he had been neutered and he appears to have a mark around his neck which may mean he had a collar on before so he might be owned. He is so sweet and he has a lovely cuddly nature. If you think this maybe your poor old puss please message us. Thank you x
