Thanks for getting back to me, Kate. Yes, it was hard to tell the cat's actual colour in the photos you posted. Also the markings on the top of his head look darker than Muta's. The bushy tail didn't sound right either but tails bush up when they're rattled! Muta is small for an adult male so looks young, but he's 5 years old. Oh well, we'll keep hoping he turns up. Thanks again for taking time to post and respond. Best wishes, Anne
