When BonnieKat was still around, I'd board her and Herald at the vet - she was hyperthyroid (meds 2x daily) and Herald was insulin dependant diabetic. They both had their favorite vet techs twisted around their little paws. When I lived in Louisiana, the vet had a boarding facility ("spa") so the kitties shared a "condo", were not in a steal cage.

Zoom-zoom, I was where you were, wondering "when is it time." Got to where I fought with Bonnie to eat, force fed her on occasion. She got scary skinny. I talked to her vet, fretted here, but when getting her to eat got to be a real challenge; she'd cry for food, but the bowl was right by her; we decided it was time. I'd watch Bonnie sleep, just to see if she was still breathing, sometimes wishing that she'd just pass away so I wouldn't have to make the decision.

I hate to say it, but you might be there for your beloved Lola. Something to consider, that her vet asked me: Does she have more bad days than good days?

There's no point continuing the battle when the bad days far out number the good days, especially when every day is a struggle, and because of age, you know they aren't going to get better.

I feel for you. Can only offer zen hugs. I know this is a painful decision.
