Re: sinus infection... My tommy had pus coming out of his right eye... The vet found a hole in the upper jaw into the sinus cavity, not caused by a missing tooth! He was put on clavamox and injectable Baytril, and for 4 months was ok. Then it looked like a lump under his cheek, on a friday night. I put him back on the same anti biotics until monday or tuesday when the vet had room to see him. I reasoned it might not be the right meds so asked for a suseptability culture to see what bug we were fighting. It was the best $78 spent as 2 days later it was a staph infection needing penacillian. That finally nailed it. With people or little ones, it is always a good idea to do a culture to see if the right med is being used.:) -- the ferret store no longer is in business,. Timmy's tonic is only available from myself, give me a call, the number is on the recipe page at timmyferret dot org. take care, Gary h [Posted in FML 6969]
