Hi...thanks for replying. I'll try warming up his food. What would be the cause of the 'foamy' vomit? The vet gave him 2 injections yesterday - .80 Convenia and Rimadyl. Is one of those an antibiotic? I forgot what she told me. One was for his fever. Our vet clinic is closed here on Wednesdays. If she doesn't get back to me tonight, he won't be able to see her until Thursday morning. With his fur feeling cold, is that an indication of fever as well?
