I am a vet tech for cats, we use prednisolone all the time...here is my dilema: Janis has canker, I am tube feeding her due to the large plaque/lesions keeping her beak from closing correctly, she has been getting 250mg of metronidazole once daily in her tube feedings. The vet I spoke with thought it would be a few weeks that I could be tube feeding her. After 1 1/2 weeks, I don't see any improvement in the lesions. She is getting pretty weak still. I have noticed that she has lice and began treating for that with the permethrin dust this past weekend. I also bought her some whole kernel corn pieces since I saw her actually pick one up and eat it yesterday. She wants to eat and hangs out with the flock and seems to drink just fine. Anyhow, after reading about trichomonas and why the plaque/lesions form (auto-immune response) I thought, "why not pred?" If it were a cat and it had mysterious lesions, pred would work. I just want to give Janis all I've got. I realize my question is a bit technical, and there is a dose for birds in the vet drug handbook, but after all this work I would hate to find out that it was a bad idea. any opinion is good too!
