I saw a message earlier today on this ng (I think!), from a person whose cat was injected with Depo-Provera, a female hormone, to stop his spraying (I think it was a male cat). Having heard about the terrible side effects of Ovaban, also a female hormone, I was curious about the effects of Depo-Provera. I posted a message to a veterinary list, and my suspicions were confirmed. A veterinarian wrote back and said that, along with feline diabetes and mammary tumors, Depo-Provera and Ovaban are known to cause damage to the liver and also to the adrenal system. He said the damage to a cat can be reversed, if caught in time. He also said that Depo-Provera has not been approved for use in cats (?).
Has anybody else heard from veterinarians or from cat owners about the dangers of using female hormones to treat a spraying cat? My own veterinarian will absolutely NOT prescribe either Ovaban or Depo-Provera, unless the only other alternative (at least, in the owner's mind) is to put the cat to sleep. She feels they are just too dangerous, and I'm coming to find out that I agree with her.
Naturally, there are side effects with *any* drug used against spraying, but it seems that using female hormones is especially dangerous. Does anybody have any experience with using these on their spraying cats?
I appreciate the info on this subject, and the time you took to ask your Vet about it. I was quite interested in knowing about these injections, and, like you, would like to hear from anyone else who has used them or has knowledge about them. The side effects you report sound awful.....I wonder if the original poster has had problems, too?

I'm a tech at a feline only clinic and we use Buspar for marking/spraying with really good results. We use it in combination with Feliway, Cat Attract, and Zero Odor. We typically only use Ovaban for Cystitis, for a period of 7-10 days at the most. It can cause diabetes, but most of the cats this happen to were borderline diabetic and the med pushed them over the edge. Ovaban induced diabetes can resolve itself shortly after cessation of the drug. More common side effects are appetite/weight increase. Never substitute information online for that of a veterinarian! Your vet knows your pet best and is the most qualified person to make a judgment call on meds. But, the more info you have the more ?s you can ask and potentially create treatment options you may not have had otherwise. =)
