My cat got a double vaccine dose by mistake. Will she be okay?

She will be fine. Dewormer has a really wide safety margin so double dosing does not cause any major issues for pets. At the most she may have a little upset stomach, but I don't even expect that to occur.

Try not to worry too much as it is incredibly unlikely that this vaccine will cause any issues with Lolly. The amount of virus in these vaccines is only enough to stimulate the immune system but not to actually cause the disease itself. For Lolly to infect the other are she would have to have the disease. Personally I vaccinate all cats for felv regardless of whether they go outside just in case they were to escape from the house etc. The vaccine won't do her any harm, but it is of course your decision whether you want her to have it or not, I imagine your vet made a mistake in giving it because it is so often done in the routine.

I'm glad to hear that Kitty is feeling better again! If her vet examines her and says that she appears healthy, there is no reason to delay her vaccine. Vaccinations are effective when given 3-4 weeks apart so that there is appropriate stimulation for both short term (IgM) and long term (IgG) antibody formation.

These two vaccines are commonly given at the same time. They are both well tolerated in most cats. Your cat, given the history, may be a bit more uncomfortable after but it should resolve in a day or two . If not, recheck with your veterinarian.

According to the veterinary medicine resource this drug has been tolerated at doses up to 90 mg/kg with mild symptoms (anorexia and excessive drinking) in some cats. Callie would have to have eaten 450 mg of Famciclovir to see these symptoms, so she is well below this amount if she ingested 2-125mg tablets totaling 250mg. She should be fine, however you can also consult with pet poison helpline to talk it over with a certified toxicologist as well. But based on my minimal research she is below the toxic level for ingestion. I hope your sweet girl continues to do well. Take care.

This can be normal. Getting vaccines can cause a cat to feel off for a couple of days. I'd just keep an eye on Baby for now. If you see a lot of vomiting, diarrhea, severe lethargy, facial swelling, hives, or difficulty breathing, that is not normal and she will need to see a vet immediately. Otherwise, this should pass shortly. I hope this helps!

Not necessarily. Some animals will have a reaction to the vaccine after being previously exposed to it. So since she already had the first vaccine, her body had a reaction to the second one. When she gets her third one, I would give her some Benadryl about 10-20 minutes beforehand. See the article for more info on Benadryl. I hope this helps! https://www.petcoach.co/canigive/cat/benadryl/
