Question:

My kitty (1 year 3 months) appears to have an enlarged heart. What can I do?

I'm feeling pretty overwhelmed and could really use some advice. I recently took my sweet kitty, Luna, for her regular checkup, and the vet mentioned that her heart seems enlarged for her age. She's only a year and three months old, and I just can't wrap my head around it. Luna's always been so playful and full of energy, but lately, I noticed she gets winded more quickly after playing. The vet suggested some tests to understand what's going on, but I'm worried sick and can't stop imagining the worst-case scenarios. Has anyone else experienced something similar with their cats? What steps did you take, and how did you handle it? I'm desperate for any insights or comforting words right now. Thanks in advance.

Answer:

Hello there,



I can imagine how worried you must be about your kitty with this recent news. An enlarged heart, or cardiomegaly, can occur for a few reasons, such as an underlying heart condition like hypertrophic cardiomyopathy, or from other issues like hyperthyroidism or high blood pressure. It’s important to gather more information to understand the cause and determine the best way to help your furry friend.



At home, you can help by keeping your cat comfortable and stress-free. Ensure your kitty has a cozy, quiet spot to rest, away from household hustle and bustle. Monitor her breathing—normal breaths should be smooth and regular. If she seems to pant when at rest or her energy levels seem unusually low, these could be signs that her heart is struggling.



Do watch for any symptoms of worsening heart issues, such as difficulty breathing, sudden weight loss, lethargy, or collapsed episodes. If any of these occur, seek veterinary care promptly as they indicate more serious problems that need immediate attention.



I recommend booking a video consult with one of our vets here at Dial A Vet. This way, we can assess her situation in more detail and guide you with personalized advice for the best care plan. We're here to help you and your kitty every step of the way!

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
