The kittens got their first vaccine on Monday, and they felt fine after that.
But, Archimedes started sleeping more yesterday, while the others ran around, very active, as usual, and when that happened again this morning, we weighed him and saw that he went down in weight 26 g since Sunday. He had a higher temperature than the other kittens, but still not high enough to qualify as fever (38.6 C). We managed to get the time at our veterinary within 30 minutes after our second call (we were very worried) and we drove there with him.
Archimedes behaved as if he were fine there, of course, he protested and yelled at the vet when the he was measuring his temperature (we have an ear thermometer, and the vet used the bad one, that goes into the rear end).
Archimedes’ condition (being tired, decreased appetite, higher temperature) is a reaction to the vaccine, as we thought.
The vet gave Archimedes an injection of saline under the skin, and an injection of antibiotics, just in case, but he will get no oral antibiotics, not to disturb his stomach flora (he is not that sick, he does not have fever. If he had fever, he would have gotten oral antibiotics as well). We also got special canned food, a/d® Canine/Feline Critical Care, to give him a little bit every few hours, diluted in water.
Poor Archimedes. The vet said it is because he has a strong immune system, so the body is fighting and he got a stronger reaction than the others.
I am so worried in spite of what the vet said. Archimedes is sleeping next to Jocke on a pillow now, isolated from the others, so they would not wrestle him. We fed him once, he did not like the food that much, but he got it in the mouth and ate it anyway.
I hate vaccines. Necessary evil. It is not the half-dead virus, it is the additives that most cats get reactions on, like people and human vaccines. It was Nobivac Tricat he got. I hope he gets better fast. The veterinary said he should.
