Welcome! My name isXXXXX am a UC Davis graduate, and currently, a Medical Director of a veterinary hospital.
I am sorry to hear about this concern for Cheddar.
First, that intermittent diarrhea.
My primary concerns for diarrhea with or without blood include:
- Dietary indiscretion (eating something you do not know about)
- Stomach or intestinal foreign body
- Something that was given to them (new food, new treat, human food)
- Intestinal parasitism (not just the worms, but the microscopic bugs like Giardia and Coccidia). They can cause vomiting also.
- Toxin exposure would be less likely, unless you have reason to suspect exposure to a chemical.
- Less commonly, endocrine diseases.
- Generally, in older pets, I am also concerned about organ disease (liver, kidneys) and cancer.
If the diarrhea is happening even weekly, that could be enough to cause some rectal irritation.
Another concern for rectal irritation would be if her anal glands are impacted or infected. Cat Anal GlandsAnal Glands
It would be okay to apply some hydrocortisone cream to her rectal area. Any generic hydrocortisone would be fine. If licking a lot, a vet is going to suggest a cone head at least for a few days to give the area some time to recover as well.
Anal glands will be easy for the vet to check, and express the glands if enlarged.
Some additional basic testing may also be suggested for this intermitent diarrhea and because she is 12.
Possible tests may include:
1. Abdominal x-rays to look for foreign bodies, masses, organ enlargement and intestinal wall changes.
2. A basic blood test for an overall health assessment.
3. A fecal test to check for intestinal parasites (not just worms, but also microscopic bugs like Giardia and Coccidia)
Please let me know if there is anything I did not cover for you. I hope that information has been helpful.
