Greetings, Irene, and welcome to my blog 🙂

Regarding your question: Yes, and Iris’ symptoms were, or so the vet surmized, a reaction to the vaccines. There was a gap of several days from the time of vaccination until when she showed her symptoms.

What our vet told me is is that this kind of reaction to vaccines happens occasionally. The way it “presents” is as atypical lameness accompanied by general depressed responses: sort of like the cat is fighting a flu bug or something. Usually it doesn’t happen again with future vaccines. It’s more or less an immune system response.

Iris is fine and continues to get into all sorts of trouble every day: I am probably a bit over-protective of her, though! Hopefully your kittens are doing fine…
