My 4 year old Ragdoll has had badly inflamed gums for approximately two years. Nothing seems to help. One vet suggested that the breeder's household of cats had Feline calicivirus and that this lingers on as inflamed gums. She developed this inflammation after having her first batch of kittens. She is now desexed and has no feline companions. Does anyone else have this problem? Does anyone know how it can be heplped?
