I am sorry i cannot help you with names, but can tell you when Ash went for his dental 16mths ago at 14 yrs old and his bloods showed he was in early renal failure, they used a special type, a human one,i was told,that is really all the information i was given, but i think it is light compared to others,I am sure Fister will be just fine and come through it with flying colours, but i know how one worries about our furbabies, will be keeping all paws and fingers crossed here for Fister.
