Hi, I'm new to this forum. I'm wondering if anyone has had experience of the following. My cat had his booster vax (nobivac tricat trio and nobivac felv-first time he's had nobivac) a couple of weeks ago. A few days ago I notice he has a large hard
lump on the back of his head/neck. The vet doesn't know what it is and has suggested putting in a needle and taking cells if it doesn't go down on its own. I'm not saying its the vax but it is a coincidence. He is also microchipped so maybe this has moved? Has anyone any ideas/views? Thanks.
