Timothy had his last annual in October 2022. No signs of a murmur then.

He had his first shot of solensia February 1st. I can't remember if they listened to his heart then, I don't think so, we were there to get his eyes looked at - he's got some colour changes that need to be monitored, I forget what it's called, but it doesn't look bad, we're going to continue to monitor for now.

Anyways, he had his second shot yesterday (March 1st). We're seeing some improvements with the solensia which is really nice.

The shot was with the vet tech, who listened to his heart, took his temp, gave him the once over. He listened to his heart, listened again, went out, came back in, listened again, and then said 'I hear a heart murmur, I believe grade 2, we have no prior history' (this July we will have had Timothy for 6 or 7 years I THINK, so there is fairly comprehensive history. He turns 15 in October). He got the doctor to come in and give a listen, and she concurred.

She said as grade 2, we can monitor, though of course that won't tell us WHY it's suddenly appearing. Timothy is a pretty calm cat, even at the vet.

She said if we want, we can consider an ultrasound, but I remember when our last dog to pass (we have three dogs currently, and Timothy and Cordelia the cats) had heart stuff them quoting around $700 for an ultrasound, and that was over 4 years ago (we ended up going to a specialist with him).

Anyways, we don't have the cash for that right now (I would expect with inflation etc. it to be significantly more expensive), and I'm not sure how helpful it would be at the moment anyways.

I'm not sure what I'm asking. Many of my cats have had murmurs, so I'm not panicking, but I'm wondering if there's anything we need to be aware of.

If it helps, he has arthritis (hence the solensia). Eats Hills oral care (but he'll eat ANYTHING - Cordelia is pickier; when we adopted him he ate various grain-free wet foods, and then different grain-free kibbles, mainly Acana, before switching to Pro Plan and now the oral care) and we're restarting fish oil. When we adopted him he weighed 23.4lbs (somewhere here there is a thread) and weighed 13lbs yesterday. He's at a 'healthy' weight but given his arthritis I wouldn't mind him losing a bit more.

I had a cat who had a heart murmur ever since I had him (he was 5 and we lost him at 18). The only time it really made a difference was when he got older and we needed to put him under for dental cleaning. We had a cardio (maybe it was echo??) ..something...gram (but I think it was basically an ultrasound) done then. I think we paid about $500-550. This was a couple years ago. They never suggested we do this when he was younger and had dental cleaning done. We now have a 15 year old hyperthyroid cat and the vet just recently told us they detected a murmur (we've only had him 2 years). They just said we will need to hold off on dental cleaning and/or do the same thing we did for our other cat. I would maybe ask your vet if they think this is something he actually needs to have done right now or if it's just something that you need to think about for the future? Maybe that would help give you a better idea?

Thanks Mac and Cats Mac and Cats - the vet said it didn't need to be done, "unless we wanted to get curious" (but that they don't think it's necessary for now). We'll hold off. I think Luc, our dog, had a ECG but I don't remember now. Vet stuff in Toronto is expensive! Ah well. Something to save our pennies for.

Did they consider doing bloodwork for him? It's common in older cats to develop a heart murmur on the onset of hyperthyroidism.
He had bloodwork done in October and all looked fantastic. I would be surprised if he's hyperthyroid based on his weight (he'd gained a bit, we've mostly got it back off now though). But - that's something I'll ask them about next time we're in, in a month. Thanks! That's a great idea.

One thing about hyperthyroid is they don't always lose weight to start. Our other 13 year old female cat was diagnosed several months ago with hyperthyroid and she actually gained weight. We only caught it as quickly as we did because I noticed she wasn't acting like her normal self and took her in right away. The vet said that in the beginning some cats will gain weight because they are eating more. Had she gone untreated for awhile, she probably would have lost weight eventually. Our other cat was found as a stray and then turned into the shelter and he was skin and bones. He had probably been untreated for a long time. We found out he was hyperthyroid the day we took him home from the shelter. Not saying that your cat has hyperthyroid. I just wanted to chime in that it isn't always the case that they lose a lot of weight in the beginning.

Oh I didn't realise that - that's really good to know. I'm definitely going to raise the possibility with them. Geez, now I'm second guessing how quickly he lost the lb he gained from October-February 1st (he lost .8lbs in February - we were trying to get the weight off, but yeah). We've always controlled intake though, he was morbidly obese when we got him and he will eat ANYTHING so he is not a cat that can be free fed. When we switched to oral care in the fall, stupid us followed the bag's recommended feeding guidelines (we KNOW better!) and he gained a lb but little Cordelia gained 1.4lbs! (She went from 8.4lbs to 9.8lbs!!!!) Timothy went from 12.8lbs and 'don't have him lose any more weight' (he's also a big cat, tom until around 8 or 9 years old) to 13.8lbs and yesterday back down to 13lbs. I'd like to see him get to around 12.5lbs but that's just me.

I've had the opposite problem! I've been trying to pack on the pounds for our hyperthyroid boy. His hyperthyroid is treated and under control, but he has been so picky since we've had him. We think it is due to suspected IBD (or SCL). He's up to 10.5 pounds since we put him on steroids! I know it's just the steroids, but I'm trying to get him to gain as much as possible while we can. It's nice not to be able to feel his little spine when we pet him. 😭 :yess: Our female hyperthyroid cat has always been a pound or two overweight. She should be about 9 pounds, but she's up to 11 now. I'm trying to get her to lose a little bit, but she keeps eating her brother's food. I am hopefully getting our third microchip feeder in the mail on Saturday to solve that problem!

BTW Our female cat just had her third shot on Saturday and it has helped her TREMENDOUSLY. She is so much more active and seems so much happier now. I'm glad it's helping your kitty too!

Mac and Cats Mac and Cats that's fantastic you can't feel your boy's spine anymore!!!!! I have a smile on my face now.

(We have to feed Cordelia on the counter - Timothy's not confident jumping up there - or he'd take her food. But since we cut back what we feed her too, she's not leaving food in the bowl)

My GA cat Nico developed a heart murmur two years back, and we couldn't figure out why. He had no prior history either. At the recommendation of the vet, we had his blood pressure checked. Wouldn't you know it, it was high! Two months after starting Amlodipine his BP was normal and the heart murmur went away. (We had no other indication he had HBP other than the murmur.)

I agree, grade 2 is not much to be overly concerned about, but it could be hyperthyroidism or high BP causing it.

Thanks! Something else I will raise with them next time we're in.
