bad reaction to vaccine?? When to worry?!

post #1 of 11
Thread Starter 
Hi everyone,

I took Cello and Kismet for their checkup and vaccinations yesterday. The vet told me that they might be sleepy and lose their appetite a bit. And if they threw up once that was OK, but more then once was not OK.

They got their shots around 5pm last night and they were fine. Came home, were eating treats, ate their dinner, then both ate their bedtime snacks around 10pm last night, were their normal cuddly selves etc.

This morning cello didn't wake me up demanding food. I found him hiding under the table, he had puked (I think just once - one big pile and two little piles) and he won't eat. It is the NEXT morning, it's been about 16 hours since the shots. Should he have had a reaction right away? Are they normally delayed? And when do I start to worry...

I'm heading to work now, but my brother is home with him and I told him to call me if he puked again.

If he is having a reaction how long should I expoet it to last and is it possible it could get worse?

I would double-check with the vet. Also, make sure he doesn't have a fever, and isn't extremely sensitive to being touched.

I'm going to call as soon as they open, but that's not for another hour, so I thought I would post here.

He doesn't mind being touched, his eyes, ears and gums look normal....... but he is VERY lethargic, which they sort of warned me of, but I just don't know if the reaction is supposed to be this delayed or how long it might last

We had a similar situation with Sterling. When we got up the next morning, he was hiding in the closet, had a high temp, and fussed about being touched. The vet gave him a shot of...maybe metacam?...and in an hour or two, he was fine. But it was scary.

In my experience the reaction my kitty had was delayed. He was perfectly fine the first day, but then the next day he was really lethargic, had a fever, but he still ate and drank normally. I am a little worried that your kitty threw up- but if the vet said it was okay if it happens once then it should be okay.

How did you check his temperature? I don't have a thermometer so I guess I'm out of luck.....

If he is still acting like this when I get home I'll take him to the vets, because that will be 24 hours since the shots...... Unless the vet tells me otherwise.

Did your cat vomit?

Thanks, I feel better that your kittys reaction was delayed as well. I am at work but my brother is home all day, and I told him to call me if Cello threw up again. He is prone to throwing up, so I would expect if that's a side effect for something that he will get it...... but I'm still worried because he didn't want breakfast at all. He did eat last night, both meals, so I'm not overly concerned about him not eating yet..... if he doesn't eat by tonight though he is going to the vets.

No my cat did not vomit, he was just really lethargic. I didn't check his temperature but his paw pads were extremely hot, and he was generally much warmer to the touch than usual...It was pretty obvious to me. His reaction actually lasted for about a week, but that's uncommon. He was just really sore at the injection site and cried when I touched him there, and lethargic, no other symtoms.

Yea, I think your kitty is fine. As long as there is no continuous vomiting and diarrhea. He will probably eat sometime during the day and if he doesnt' you can check with the vet. Here are some vibes that this reaction is over as quick as possible

Sherman's was delayed. He was fine that night, somewhat ok that next morning, but by lunch was very lethargic. I knew something was wrong because he's normally a fussy energetic cat - which he wasn't.
He turned out to have a fever of 104.3F - 105F is bad for those who don't know, that's when one has to worry about brain damage occurring.

See my thread from about a week ago for more details.
