great to see that run of greens! he's doing well.
do you need info on prepping for the dental? i'm not sure if anyone's given you any yet.
your vet will advise you on what to do with the insulin dose the morning of the dental. Some want no insulin, some want a half-dose. I'd follow your vet's advice on this because that's what s/he is used to working with. Anesthesia can drop blood sugar, so it's important to manage that part carefully.
Get a test in before you leave him at the vet's and as soon as you get home. that'll give you a baseline for the rest of the day.
you'll want some baby food on hand - meat and broth only - for when he comes home from the dental. the anesthesia can slow down their gut motility, so feeding a little bit (1-2tsp) of that every 15ish minutes for a while will get food into him while being easy on his body. nothing else in the baby food.
you probably want to ask for no metacam - it has a black box warning on it for renal failure in cats, but it is approved for a one time use post-surgery. most people ask for Bupe instead. I think that's Buprinex. You can do oral bupe by putting it in his cheek pocket, or up on his gums, or it can be injectible. If he has much work done on his mouth maybe the first day on injectible would be easier on him. you give it just like insulin, same syringes.
you might also want to ask for no Convenia to be given. Convenia is an AB that was developed for skin infections. It's used for other things, though, because it is "convenient." one shot lasts 2 weeks. The problem only arises if a cat is allergic to it - then you've got a 2 week problem. the typical ABs for cat dentals are clindamycin and clavamox. If he has teeth pulled you'll probably end up with some kind of AB. If so, you might need a probiotic to counter any diarrhea problems - clindamycin especially. Probably the most common one people here use is Fortiflora, which can be sprinkled on the food and most cats love. You can buy it from vets or online from Amazon.
if you haven't pilled him yet, the Duck and Pea Pill Pockets FOR DOGS are safe for diabetic cats. i have my cats trained to eat little balls of them if i toss them on the floor. the stuff is like playdough. then when i need to give pills, i wrap them in the pill pockets and throw them on the floor. far easier than our former "stick it down the throat while i grip you in a hug" plan. :lol:
hmm, those are all the things i'm thinking of off the top of my head. if you put "dental?" in your subject line in the next day or two people will give you all their best tips on how to help Frank get through this as easily as possible.
It is always so nice to read about his constant improvement, thanks to you and DH. Now I'm thinking that since he is feeling so good and preening like a king...maybe a picture of the new and glamorous man will emerge??? ;-)
