Hello,
I’m sorry to hear about your cat.
In my experience constipation in cats is always secondary to something else. And in fact very few are actually constipated. It is absolutely imperative that someone competent palpate your cats abdomen or take an Xray to confirm the constipation before you treat for it. People always think it’s constipation and it’s usually poor dietary intake, cachexia or poor muscle mass and usually a few other things.
Constipation in cats feels like a colon full of hard distended feces. This should be confirmed by a rectal exam. The problem with getting this diagnosis incorrect is that all of the things you try to treat it will make everything else inherently worse. Do not give your cat anything until you confirm this and figure out why it happened.
My guess might be you don’t have the diabetes adequately controlled and therefore you are losing muscle mass. This includes the gi tract which can no longer push feces out of the body.
Please find a vet you trust for your cats care.
Hello,
I always advise unblocking and leaving the urinary catheter in for about 3 days whilst giving iv fluids. It helps flush the bladder (and whatever caused the blockage) and diurese the kidneys which are usually impacted. I do not advise unblocking and then removing the catheter. Both cause more trauma to an already traumatized urethra.
I also advise transferring to your own vets office for Care of the er is too expensive.
I have more information on this subject on my blog KMDVM.blogspot.com.
