Cat with epilepsy/heart murmur suddenly grumpy. Is it medical?

Updated on September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 2 years and 4 months old | 11 lbs

Kovu has recently been diagnosed with epilepsy and a grade 3 heart murmur-for which he’s getting an echo next month. I’ve noticed that he’s been unusually grumpy with my other pets recently as well. every time another pet walks by them he meows and smacks them (no claws out though). He even went over to my dog just to smack him when he normally wouldn’t do this. He used to play with my puppy but he smacks her now if she tries. Could this be medical related? does he need another vet visit?

I hate to hear this is happening to Kovu. Yes, I would say this could be medically related if he feels tired or just not himself. Make sure to bring this up at your next veterinary visit. make sure Kovu has lots of down time as well to rest.

Lastly, here is a great article about cat's instinctual needs:

Use a Feliway diffuser, set aside 30 minutes a day for attention for Kovu and/or ask your vet about switching the food to Royal Canin Calm. Most cats response best to combination therapy. The veterinarian can also prescribe medications which can help with stress if really needed. I hope this helps and please feel free to post any additional questions.
