Question:

Saddle Thrombus - How Common is It?

I'm feeling pretty overwhelmed right now and could really use some advice. My cat, Whiskers, just got diagnosed with a condition called saddle thrombus. I've never even heard of it until today, and it's breaking my heart to see him in so much pain. The vet explained that it's a blood clot that's affecting his back legs, and Whiskers is having a really hard time moving around. I'm trying to wrap my head around all this and wondering just how common this condition really is. Has anyone else dealt with this? Any experiences or advice would be incredibly appreciated. I'm worried sick and just want to do everything I can to help my little guy feel better. Thanks in advance for any guidance or support you can offer.

Answer:

Hello there,



I'm really glad you reached out with your concern about saddle thrombus. It might sound like an uncommon term, but understanding it is important for your cat's health. Saddle thrombus occurs when a blood clot forms in the heart and travels down to lodge at the point where the aorta branches to supply the hind legs. This can cause sudden pain and paralysis in those back legs.



While it’s more common in cats with heart disease, like cardiomyopathy, it can sometimes occur in cats without known heart conditions. Cats from middle to old age are more susceptible. The signs can be quite distressing, including sudden inability to use the back legs, loud crying due to pain, and cold, bluish paw pads.



At home, it's crucial to keep your cat calm and warm. Avoid manipulating the affected legs to prevent further pain or injury. Unfortunately, this condition often requires immediate veterinary attention. Watch for any signs of struggling to breathe or significant distress.



If you're seeing any of these alarming signs or suspect a saddle thrombus, please seek veterinary care right away. A vet consultation will be the best way to assess and manage your cat's situation. Consider booking a video consult with Dial A Vet for timely advice from professionals who can guide you on the next steps. Your quick action can make a big difference in ensuring your cat receives the care it needs.



Take care.

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
