Pet's info: Cat | Mixed Breed | Male | neutered | 5 lbs
I adopted a young male cat from the shelter. He then got FHV so I took him to the vet and was given amoxicillin. He got better, then 2 weeks later got sick again. Our vet gave him a refill, but after 5 days of no improvement, I took him back and was told he now has calicivirus. He was given (attached picture), but it's been 3 days and his health is declining. Vet visits are adding up $$$ and I don't know what else to do! :(

Hello, thank you for your question about Cairo. Based on the symptoms that you are describing it sounds like Cairo is suffering from a bad upper respiratory infection. Viral upper respiratory infections (secondary to herpesvirus, calicivirus, etc) are not uncommon in cats adopted from a shelter. Flare ups of these infections are usually brought on by stressful situations, such as a recent environment change/shelter life, etc. If the infections become serious they often lead to secondary bacterial infections and possibly pneumonia. If it has not been done already I would recommend having chest x-rays to look for evidence of pneumonia. Additionally, I would recommend discussing a different antibiotic with your veterinarian. Convenia, is not routinely used for upper respiratory infections/pneumonia, and could be contributing to the progression of the symptoms. Hope this helps, good luck!
