I think it might be Thunders time to go?

Aw, poor thing.

I had the same thing with Mist where they didn't know exactly what was wrong but he suspected a heart block problem. I didn't think it fair or worth it to put her through loads of tests so I had him put her to sleep there and then and it was horrific. I'd made my mind up about that the day before if it was something that couldn't easily be treated. The vet sounded like he didn't reckon it was worth doing tests either.

Anyway, that was a year ago and I'm welling up now just typing this so my sympathies with you and your family.

My thoughts and prayers are going out to all of you. I'm so sorry

It's heartbreaking to watch our beloved furbabies suffer.You have given him a good life, and the kindest (if hardest) thing is to lovingly release him. He'll be watching you from the RB, nice & healthy again.
You'll be in my thoughts & prayers.

I'm so sorry. Thunder has had a wonderful life with you and your family. It's a hard thing to let them go, but sometimes the best thing to do. You will be in my prayers. {hugs}
