Thanks for the feedback all. Medusa...400?? wow, thanks for sharing Pigeon's story. Give her some gentle kisses for me. Phinehas is only 3 years 7 months old. My vet did mention beta blockers as a treatment depending on how severe the condition is.

kb2yjx, that's great that Riley is doing so well! I hope this is the case with Phinehas. Depending on what the heart rates are when I take them here, my vet may want to see him again and prescribe meds, or just wait for 6 months to do a recheck. I'm really hoping for the latter and if all I have to do is check it every few months or every year, that would make me happy.

Jen, how is Shilo doing on the medicine?
