Hi Kim
I'd also go ahead with the scan if it were me. I'm the sort of person that likes to know exactly what's going on. What can we do, eh? We have them and when they're ill we have to help them... that's the way it is for loving, responsible pet-owners. Somehow we manage to find the financial means because we love them.

I'm so sorry the little fella's ill, it's so heartbreaking when any pet has a life-threatening illness, but when they're only little, it's just not fair. Looks like he's in really great hands, and isn't it amazing that we can now refer them to cardiologists and the like these days?! One of my cats saw an eye specialist over here in Italy. It's amazing what facilities are available...

A big kiss and a stroke for Sweep from me and the felines, and a chin up for you xxx
