My 10 year old cat, Fluffy, was recently started on an aspirin regimin (81 mg every 3 days) as part of a treatment plan
for hypertrophic cardiomyopathy along side
diltiazem every 8 hours. After about 10 days of this treatment, Fluffy started to display obvious signs of intestinal distress, including heaving, vomiting, and diarrhea, we called the vet, and he said to cut the aspirin dose in half, and if Fluffy is still having problems, administer pepsid twice a day as well.
