We have a older cat he is 14 and he has upper respiratory, we got him an antibiotic and he got pretty sick on it throwing up and diarrhea can i give a weaker antibiotic? and will it still get the infection, plus there is another cat outside should i give her the antibiotic too?
You have to talk to your vet about this. Maybe there is another medication that your pet will respond better too. I can not tell you to medicate an animal without first examining that animal. vetcare
