Sorry to read that he's in the hospital. Can you paste the details from your FB? Not all of us have FB accounts.
Last post here, he was dealing with pancreatitis.
On the 24th he threw up and would not eat. 25 th took him to ER. They gave him fluids and anti nausea shot and appetite stimulant. Came home with cerenia2 pills, and gabepectin . Ate a little that night (sunday) .. gave Cerenia mon, tues, Wednesday and Thursday. Since he was eating so well I did not give him Cerenia Friday.
Saturday 30th threw up and would not eat again and hiding. Gave him Cerenia and he ate some. Sunday July 1 same thing. Monday July 2 back to ER. kept him with iv fluids etc. apparently needed more than out patient care.
He got his insulin that evening but dropped very low the next day so no insulin. Apparently 9 U is too much so last night they gave him 7U lantus.
This morning he was 100 and was not supposed to get insulin but the tech (who I hope was fired) took it upon herself to give him 7 U a half hour before the doctor arrived. Reported to staff and management and like I said hope she was fired). So staying again tonight and the ER vet will consult with his internist there for a plan when he comes home hopefully tomorrow evening.
I could not even eat this morning so stressed.
we did visit with him yesterday for 1/2 hour
Second question - generic glargine is interchangeable with Lantus. Just make sure it's not past it's expiry date and has been kept in the fridge.
First question/topic - sounds like they are trying to differentiate between IBD and small cell lymphoma. Don't let that last one scare you - it is treatable and many cats go into remission with proper protocols. The two have someone different treatments, which is why you want to know which is which. Neko was my second of three cats that have had thickened bowels. She could not have endoscopy or biopsy because it involves anaesthesia, and her heart would not allowed that. So the IM vet (in consult with an oncologist) made an educated guess and we treated for SCL. Third cat did have an endosopy, though she is younger. It's a pretty quick procedure, in and out in the same day. However, the bowel thickening has to be in the right place for endoscopy to be able to reach the right tissue for biopsy. If not, then a surgical biopsy is required. I belong on a small cell lymphoma (SCL) group that has had lots of cats, also older than 13, successfully have the surgery.
One hiccup I see with doing surgery is that being on steroids (budesonide is one) can mask the problem, and mean that the endoscopy (or surgical biopsy) would not get a good result. Best to have them off the steroid for a couple weeks before doing the procedure. And most important, make sure his heart can take the anaesthesia. I would recommend a heart workup first.
If he continues to not eat, they may suggest a feeding tube be put in. Again, a fairly common temporary solution that can help him until he has a proper diagnosis, and treatment can begin to make him better.
What is the Pepcid for? This might not be a good drug for him if he's got a GI issue. I would also recommend a GI blood panel be done. Many cats with either IBD or SCL are low on B12, so he may need supplementation.
A GI panel would tell you if you need to supplement with B12 or not. It would also show folate, TLI and SpecFPL (pancreatitis test).
SCL treatment is a steroid to start, possibly eventually tapered, and a mild chemo pill every couple of weeks. Over time that chemo pill may be discontinued. You might need to give ondansetron the day of and a couple days after the chemo. If IBD, then diet is important, there may be food allergies. So it could mean a novel protein, and also need to give a probiotic. Visbiome is a good one. There may also be a steroid, but not always.
WD is high carb food, no need to give it. You can go back to Fancy Feast if he's eating it.
