Took fattycat along to the veterinary hospitality just for a health check as Snorg was going. And I'm a bit neurotic about her now! The vet suggested doing an ultrasound scan if her heart, as she has a murmur. It's been mentioned at my normal vets previously but nothing else said about it. She's 6 and fit and healthy and doesn't seem to cause her a problem. The vet admitted that she is very pro scanning and would scan if it was her cat. But it's my choice. Really not sure if it's worth doing or not. It's will be about £300 ish. Which isn't a huge issue.
