My Kaycee insists on drinking water from the tap, and he doesn't care if it's the middle of the night and people are trying to sleep. I'm trying to persuade him that the water in the toilet is a perfectly good substitute and he has tried it a couple of times, but me holding the faucet is what he likes best. Every cat has its own unique personality, and it's great fun to discover what it is. I'm sure that Angel was an interesting cat with her own way of looking at things. I know you saw a lot of difference in her personality as compared to Tigger's.
