Yeah, every cat has it's own charm. Like how munchkins have shorter legs, or american curls have funky ears (yes there's an american cat like the scottish fold ), and so on. >w< No, but I do sometimes. And I'd probably draw her indecent a lot less if I had to do so without the tail. XD
I think tailless is more unique. But. The markings both the cats seem unique as well. (At least that's what I think) It is your decision. It's not like you can't turn back if you don't like one or the other. lol
I was thinking of making it optional, but in that case I want to keep the different anatomy of both versions. 'Cause the different anatomy of a Manx was one of the reasons why I was considering that breed :3 I like your idea though!
