Just read that webpage - I think that may indeed be it! I always thought there was 'a bit of something' in them. They've definitely got different fur to most cats I have seen. Rossi is silky smooth but Casey is a bit coarser. But I think Rossi is the better groomer, so it may be down to this. Yes, it's fab having the two of them. They are amazing company for each other. Even now, almost 3 years on, I hate leaving them in the morning. But if I pop home during the day, or come home with some work, they are not happy that I have disturbed their routine! They are always fighting, they have a love-hate relationship. It’s so funny that they can be going at each other hammer and tongs one minute, then the next they are in full grooming each other mode! If one dares to go wandering over the fence though, the other will be on edge and be chattering away to me until they return - aren’t they such funny creatures?!!
