Hello,
The answer to this depends on a lot of things. Like age, degree of trauma , other neurological deficits and post op time.
In general cats are very resilient and even if they don’t fully recover they often manage their challenges quite well.
I guess my advice is to not give up but know what you are dealing with. Palpate the bladder multiple times a day and check a urine anytime it smells bad or looks murky. Keep encouraging walking and playing. Nothing rebuilds muscle better than that. Learn to palpate the colon. Add water or a laxative (not fiber as I feel it just adds bulk and makes defecating harder) to help the stool stay soft and easy to pass. I hope this helps.
Hello,
The diarrhea has a cause. Until you find out what that is you are simply trying to resolve a clinical sign.
If your dog isn’t on a heartworm prevention that treats for intestinal parasites you should ask your vet to look for these. If your pet is young and unvaccinated I worry about parvovirus. If they are old I worry about disease and deficiency. Your dogs weigh tells me nothing about what the cause might be. Please call a vet and get better help to resolve this. Chronic diarrhea can cause dehydration, emaciation and even death.
