Back from the vet!
She came home with me
But I'm certainly not in the clear yet. The next 24+ hours are going to be scary.
He took a look at her and said that she is not in pain, she is just tired. Good. He said, it could be a number of things. She could have organ failure, just because she is old and her system is just shutting down. Her breathing is very laboured and he thought that could be because of a uri, pneumonia, or she could have masses in her lung that migrated from her other 2 masses. And her heart rate is low which could be a result of compromised lungs or organ failure.
SO he said since she isn't in pain, he didn't feel it was necessary to euthanize and we decided to give the antibiotics a go. If she seems to be in pain tomorrow he said just call and he will take her in whenever necessary.
So all in all, I'm very lucky to have more time with her. I thought hard when I was on my way home for things to tempt her to eat and came up with cheese sticks or cream corn baby food. Well the cheese sticks she didn't bother with but she had almost a full 1mL of cream corn baby food so I couldn't be happier now. I know that that means nothing, but I am happy just to get food into her
