Is Claudius a Tonkinese? I had a cat who looked SO much like him (but with blue eyes). They are both handsome fellows!
Claudius has the prettiest green eyes ever.
Claudius is a Russian blue and Nicholson--according to the vet's best guess--is a Siamese/orange calico mix. I think she must be the one you think resembles a Tonkinese? Her eyes are blue like a Siamese's, but I have NEVER been able to get a decent picture of her eyes. You should post a picture of your Tokinese!
