What an awesome idea Noc!
I've looked in my pedigrees as well: no luck

I can imagine it is indeed a lot of extra work but só woth it I think because there is much pain behind the keys/ screen of people who have lost a cat.
In fact the very reason I breed cats is because I lack the joy of having a real cat due to allergics so these virtual buggers are really my babies.
Luckily I have good news Deer shared with me she has the heaviest allergies ever but it seems a Balinese or Siamese doesn't give those reactions in most cases.
