I had heard of a cat straying into a garden,albeit fully fenced and secure,but unfortunatley for the cat, it was killed by a patterdale and a lakeland terrier who lived at the house and just happened to be in the garden
The police were called by the cats owner and the outcome was, cats chase and kill mice, dogs chase cats, theres nothing we can do as,the dog was in its own securely fenced garden, it was the cats owner that was at fault,in allowing the cat to stray.
