I suspect one reason the Hivewire cat only has a rather limited range of breeds and colours so far is that they seem to only have a fairly small base of actual modellers and texturers. Given that the Hivewire team is currently working on a large and very varied range of animal models , all at the same times - dogs of all sorts, big cats, lions/tigers, house cats ( there's a WIP Siamese), horses, deer of all sorts, elephants, cattle and much much more, it's no wonder they get a bit behind with add-ons for already released models. But, the results are well worth waiting for :)
