We did our research when we bought a Norwegian forest cat, they were a registered breeder and had won many competitions. We assumed this was indication of a good quality breeder. We lived a distance from the breeder so reserved the kitten and went to pick him up it was December and obvious that they had multiple litters for the Xmas period, it was like a supermarket procession of people visiting for kittens! When we got him home we separated from our other 3cats to give him time to get to meet them, when we visited the vets he was very underweight and riddled with ear mites, the breeders granddaughter had also painted the kittens nails with nail varnish which they had scrubbed off with remover which had damaged the nails, the vet thought there would be permanent damage. It took about 6 weeks to sort out the eat mites which delayed the whole integration process with his new brothers and sister. He’s now a beautiful cat and has recovered from his poor start but researching the breeder doesn’t always work!
