Why is my cat vocalizing and straining when having a bowel movement?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 18 years and 8 months old | 9.5 lbs

Hi my vet has tony on 1/4 Pepcid each day this week b/c he has some GI upset from trying new kidney diets over the last 2 weeks & this morning I heard him vocalize in the box b4 a bowel movement( he was not vocal b4 urinating)..could this be due to upset stomach? He just had his 4 mth checkup, lab work, urine check & all normal except for slight elevation in kidney values) Also is it safe for tony to take an appetite stimulant with his amlodipine,methimazole & tumil K? Thx!!

Cats with kidney disease are prone to constipation so if this behavior continues or he seems to be straining in the litter box I’d recommend seeing your veterinarian. Most appetite stimulants would be safe to give with these medications but it would depend on the actual drug - check with your vet to make sure it’s okay before you give any other medication.
