He was sneezing but that subsided. He has a wet cold nose, clear eyes but a little damp in the corners. He is eating well and drinking normal. It has probably been hanging on for about 12 days. So I wondered if I should give him a low dose of Vit C? I thought maybe someone here would have some experience with elderly cat colds, and home remedies.
I would not give your cat any human drugs unless you speak to your vet and they give the okay. Your cat just might have developed allergies. If his eyes get gunky and he stops eating, then I would worry.
