Dumpy was looking a bit peaky last Monday. By lunchtime, he was wide-eyed, shaking, and couldn't stand up - his back legs just collapsed. Saddle thrombosis, I thought, and rushed him to the vet. By the time he was triaged he was fine (and very angry with them) and all blood tests and ultrasound scans* were clear, so he left with a clean bill of health. It's a mystery. The weather had been terrible so he hadn't even been out where he could have eaten anything poisonous.
*heart all good - this is a cat that one vet wrote off with hypertrophic cardiomyopathy in 2022 - his regular vet says 90% of domestic cats have a thickened heart lining because they're lazy bastards!
