Hi there, we don't actually own a Mau yet, but we have one coming to live with us at the end of March (a kitten).
The main thing that we have read and been told by breeders is that they are very playfull and love company! They don't like being left alone for very long, so if this is likely to happen the breeders I've spoken to suggest getting another cat aswell (if you don't already have one!) for them to play with - as they say, "two's company"! (and hey, sounds like a good excuse to get another cat!!!!!
Apparently they are also very accepting of being walked on a lead/harness... so thats a bonus! They need quite a bit of exercise as they're pretty energetic.
Let us know when you get new addition! All the best!
