Thanks everyone for the hugs and replies to my post, I forgot how much that helps

Our cat was diagnosed with hyperthyroidism last Saturday, which explained the weight loss and the intermittent soft poops. But 24 hours after her vet visit, she started having liquid diarrhea and stopped eating.

She seems to have turned a corner now, and she's eating and her poops are less liquid, and she's all around a bit brighter. She still needs to gain weight, but it looks like were on the way to getting her to the baseline of health she needs to be to start the treatment for Hypothyroidism. She'll be having radioactive iodine therapy, and the closest cat nuclear medicine place is a 5 hour drive away. It's expensive, and we had to ask the bank to raise our credit card limit so we could pay for it...but, we'll worry about the money later.

I did remember to ask for a b12 shot for her last night, something the vet "forgets" probably because it only costs $17 - and it's made her feel quite a bit better.

Hugs to everyone, thanks for listening/reading
