Hi I have Norwegian Forest kitten who reacted to his first vaccination It has left him sneezing first thing in the morning. Our vet has looked into his problem thoroughly.It started after his 2nd vaccine when he had a temperature for 24 hours. The vaccine used was made by Quantum. My vet says any small drops of vaccine left on the fur as the needle is withdrawn is the problem, if the kitten or otrhers lick it of they have a reaction. I have spoken to another breeder who also had a similar problem with this vaccine almost loosing a litter + her older cats who was boosted with this make were ill!Remember when the litter are taken to the vets for their vaccines they often travel in one cage, so on the way back can easily wash the drops of each others coats! Has anyone else had experiences of this kind?
