My CAT had a vaccine reaction. I feel terrible, because I don't vax my children and even had a suspicion following the cat's last round of shots. Of course nobody believed me, and yesterday he had his booster. Today, he has pulled out or lost all the hair on his right flank and part of his tail. He's limping and yells when we pick him up. I gave him some thuja, but dammit. With kids I know the protocol to not vax, but with pets, I don't. Any input. We're never doing this again. Arrrrrgh. Where to from here?
