The fast is also more important when they are in low numbers at preshot time, and you want to make sure that low number + food influence is still a safe number to shoot. No worries with Squeaky tonight.
Squeaky is on a relatively low dose of prednisolone. We have had some cats switch to budesonide successfully for their IBD, and since it's a more localized steroid, it doesn't impact the BG's as much. It didn't impact Neko's at all. I had a civvie cat on 10 mg of pred daily, and it didn't impact his BG that much (maybe 20-30 points). I think how cats react to steroids is rather individual. What you have to trade off is how well the pred is helping his IBD symptoms and whether you want to trial a new medicine. Our saying here is that if you have to give a med that raises the BG, but is needed for another condition, you don't stop that med, you just raise the dose to compensate. I get pred compounded into a chicken flavour chew treat, so I have no problem with it being eaten.
