I'm pretty sure Spike has a respiratory infection, but I can't afford a trip to the vet right now (I'm in school, haven't had a pay cheque in six weeks.) He gapes even when he's not under the lights, the other day he opened his mouth really wide and made an odd sound, almost like a yawn, and just this morning I was feeding him and he started panting and wheezing. I want him to get better, but really can't afford a vet visit. Are there any online stores where I can order something that will knock the infection out? I really don't want him to be sick.
