My senior cat ate peppermint oil. Is it toxic with kidney issues?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 13 years and 6 months old | 9 lbs

My cat ingested a small amount of peppermint oil in a CBD tincture last night - a couple drops maximum. I didn't realize it until today. She's neither thrown up nor is exhibiting any signs of trouble, but she is a senior with stage 2 renal issues. If her organs are processing this, is there anything I can do to help, such as parsley oil as a chelator? Thank you.

Parsley oil will not help in this situation. Because Sophie has stage 2 renal issues and peppermint oil is toxic to cats, it's best to get her checked out by a vet asap. I'd recommend bloodwork and a urinalysis to check how her kidneys are functions. Please take her into a vet. Best of luck.
