Thank you all! I'll pass on the advice to Dali's mom when they come back. I did actully mention about his ears the last time I catsat. Glycerine sounds like a good idea Gary - and cheap. I guess some cats just get dirty ears without nothing being wrong. He does go outside in the garden a bit, but he hasn't been out for 10 days now.

I have offered to come along to the vet when Dali is going. I do hope that all his teeth doesn't have to come out!
