Customer Question

My 2 cats got their vaccines tonight (about 4 hours ago). It was the FSC (or some such acronym). My male is acting a bit stangely. He is jumping one of his toys and making light meows. I don't remember him acting like this before. Both cats are 5. No vomiting.
JA: I'm sorry to hear that. Hopefully it didn't make a mess. Did the cat eat anything unusual?
Customer: No
JA: OK. The Veterinarian will know what to do. What is the cat's name?
Customer: Simba
JA: Is there anything else important you think the Veterinarian should know about Simba?
Customer: No. his checkup did not indicate any other causes for concern. Oh - he is neutered and had occasionally been known to hump my leg in he past

Well, nothing you are describing is consistent with any typical vaccine reaction.

The typical symptoms that would concern me are:

1. vomiting

2. facial or any body swelling

3. hives or welts on the body

4. labored or open mouth breathing.

A normal reaction would be appearing a bit lethargic or off food for 12 to 24 hours.

So, overall, at this point, I don't believe the behavior change is a concern, and I can't attribute the behavior change to the vaccines.

Just for your information:

The typical cat vaccines are:

1. Rabies

2. FeLV (feline leukemia)

3. FVRCP (also called the combo)

Hope that information helps

Hi Rhiana,
I'm just following up on our conversation about your pet. How is everything going?

good. No vomiting or any of those other symptoms listed. He was still jumping a bit the other night again, but if that is nothing to do with vaccines then that is fine - he has occasionally humped my leg in the past so that action itself is not new - the thing that was new was him doing to a toy and meowing bit more while doing it.

Does not sound vaccine related, or at least nothing to suggest a reaction.
I hope my answer was satisfactory.
