Is it safe to get multiple cat vaccinations at the same time? - The Drake Center
Yes, it is safe. And because I know most cats don’t enjoy car rides very much, the preference is to go ahead and get them all at one time. A rare cat doesn't feel well after a vaccine, just like a person who receives a flu vaccine. And in those instances, we can discuss splitting them apart, but I think that the benefits of getting them all done at one time for a cat way outweigh the multiple trips that would be required for them to come in.
Is it safe to get multiple cat vaccinations at the same time? - Freeport Veterinary Hospital
If your cat has always tolerated vaccinations well, it's absolutely safe to go ahead and get multiple boosters simultaneously. Just like as kids, we got two or three shots at a time to keep us safe from measles or chickenpox or things like that; the same goes with cats. We are competent in the safety of our vaccines, and it's actually safer to do multiple vaccines at once than run the risk of a kitty not getting back into the vet at the appropriate time to get the boosters they need.
Is it safe to get multiple cat vaccinations at the same time? - Animal Hospital of Statesville
I'd say, typically, the answer is yes. Often we do multiple at a time, but there are some considerations. Even when people get many vaccines, some people do feel more groggy or just a little sick or don't feel well in general. So when necessary for timing or certain situations of the cat, absolutely. We can and do multiple vaccines together, but that is why we split things up as they get older.
We try to rotate things. We have three-year vaccines if they can stretch out that far. We try to do, say, the rabies vaccine on an alternating year, change things up a bit so that they're not getting as much at once.
