Re: Bud update: vet visit
((((((Beth)))))) I am so sorry Bud is having problems! I don't know if you remember me from the PZI forum, but someone PM'd me since I have some experience with Leukeran and IBD.
From everything I have read or heard from vets, Leuk is supposed to work well in keeping IBD/cancer from getting worse. From what I can tell it does not necessarily *improve* things, but it can dramatically slow the rate at which they get worse. I have actually tried it with 3 cats (with all the years of dry food

IBD has been a theme in our house). The first had an uncommon reaction where it made her nauseaus so we had to stop it. With Bix, he clearly was feeling unwell despite the Leuk and numerous other meds and was still having problems with nausea, so I opted to stop it. I felt like if it wasn't making him feel BETTER, it didn't make sense to continue with it - if it would just keep him feeling unwell for a longer period of time, that didn't seem like the humane route to me. With my civie who now has intestinal cancer, I tried it but for her it has been the same as Bix - I didn't see any improvement in using it, and she still had enough symptoms otherwise that it hasn't felt right to me to continue it.
My recommendation would be that if you are comfortable with the cost and the possible side effects (which are relatively low, but you do need to get blood work periodically to make sure they are tolerating it ok), go ahead and try it if your vet thinks she should be on it. Might help, can't hurt - or if it does cause side effects, you discontinue it and they go away (as far as I know it doesn't cause lasting problems). The best price I found for it was $4/pill at Walmart. The specialist charged more like $8/pill, so it is worth shopping around.
I agree on skipping the biopsies and stuff. When I have been at the specialist I have asked a lot of questions about what difference the tests will actually make in the treatment plan, and have concluded that unless you are planning to pursue surgery or chemo (other than Leuk), it's kind of irrelevant. I've asked both my regular vet and the specialist if there is something *else* these symptoms might point to and the testing would tell us that and they kind of sigh and say well, not really, it's almost certainly going to be IBD or cancer.
For us the medicine that has been the most effective and given my IBD kitties the best QOL has been the steroids. It's a pain b/c of the potential side effects and long term issues, but they really do seem to work amazingly well for a cat who isn't having good QOL otherwise. If you are considering steriods, you can try starting with Budesonide, which is local to the intestinal tract and does not affect BGs the same as systemic steroids. That worked really well for Bix, but for my latest civie (with intestinal cancer), she did not respond to Bude, but has responded well to Prednisolone.
Caveat is I only have the IBD perspective, I don't know a lot about the other conditions you are dealing with so I don't know if for instance Budesonide would be in order - could be Pred is needed to help with other inflamation issues.
Hope you are doing ok, and I hope Bud's new suite of meds will help her feel better soon! The Bupe should at least - liquid is the only form I have seen.
If you do try the Leuk, be sure to keep it refrigerated, and wear chemo-safe gloves when you are administering it - I've been able to find those in the pharmacy section at drug stores.
