    I'm always in the cat section for something bad, the joys of elderly cats hey :(

    Boy who had the constipation got vaccinated on 16th March and he's got a lump on the back of his neck where he was vaccinated. Its loose in his skin and he doesn't seem bothered by it at first I thought it was a bit of a reaction as he's allergic to fleas but its still there and it dawned on me today its probably from his vaccine.

    Does this happen normally? He's 17 and has had boosters every year for his whole life, going to ring the vets tomorrow but expect they will say its nothing etc anyway, just curious as to why its happened...

    :eek:

    Which vaccinations did he have?

    It's not uncommon to have a reaction on the injection site ( mine had a tiny lump which lasted a few hours post steroid injection ) but I wouldn't have expected it to last this long. That said it doesn't mean there's anything wrong necessarily though I'd still run it past the vets. Keep an eye on it all the same for any changes in size etc.

    On a slightly different note-if Boy has had vaccinations all his life I'm pretty sure he's built up enough immunity by now to these viruses. I have cats of similar ages and vaccination history to yours but they've not had any shots for a few years now for this reason plus there's been some controversy about older animals and vaccines. I'd discuss this with your vet. However annual checks are important and I would continue with these.

    There's a fairly recent thread on here about vaccinations and older animals though couldn't locate it when I looked!

    If the vet included FeLV vaccine or used a killed vaccine then a lump is more likely and can take well over a week to go down. I've never had lumps form when using live vaccine only but always do when I use Pentofel with kittens.

    Thanks he was done on 16th March. Vet was very insistent he should be vaccinated and so we got him done. Not had the other cat done this year though and wont I don't feel they need it. They are predominantly indoor cats now who don't go hunting or off round fields just into the garden to sun bathe for a little etc.

    Will find out what they did him with I doubt they will be very interested in him having a lump though.
