My Russian Blue has the same (removing stomach fur) issue
My 3 yr old Russian Blue female has the same issue of removing her stomach fur. The local vet thought it was stress. I won't rule that out, but am struggling to see what may have changed to cause her to stress - or now to suddenly act out on it. The vet checked for Ringworm, and was going to do a scratch test, but then didn't (not sure why - she offered no explanation on that). The skin looks fine. Any new insite to this seemingly elusive issue?
