I have a ball python with a respitory infection. He has been to the vet and given fortaz and Iv also been nebulizing him with f10 almost every day for atleast 20 mins. He has had this infection for almost 2 month now. He is not lethargic and never was. He still has alot of energy to fight when I hold him down to rinse his mouth with saline and often cruises his tank at night. The only issue is he hasn't eaten since he had started with the infection. I have tried to feed him every week since then and he just won't eat. He's looking a little skinny lately so I was wondering can I syring him some Zilla jump start? For those of you who don't know what that is, it is a calorie supplement and appetite stimulant for anorexic reptiles. Would it be ok to give him some of this a few times a week until he starts eating again on his own?

Thanks
