We went back to the emergency vet today, and we are home. Cassie had blood work and a urine test. Her temp was 99.3 which is low for a cat. Her potassium was 3.4 which is just slightly low. The vet (different doctor than yesterday) looked at her mouth and thinks she has a mouth infection. Cassie got a shot of Convenia and 100 cc of sub-q fluids. I will be giving her 100 cc of sub-q fluids each day for 5 more days (meaning tomorrow will be day number 2 of 6). After the sixth day if she is eating well, we will go to every other day till the bag is gone (1 liter in the bag). She is drinking water and the vet said to offer her a variety of foods, whatever she will eat. Although she might not eat well for another couple of days. They took a blood sample for thyroid testing, but that is done off-site, so the results will take a few days. I am to call Wednesday to give an update and get the thyroid results, and we go back a week from Wednesday. At that time one of two things will happen, either she will get another dose of Convenia or they will schedule her dental work. One question, I thought they could not do the dental work because she is too thin for anesthesia. But I might have misunderstood. We will see the different docs in the practice (4 docs see patients for appointments and 2 or 3 handle emergencies) as we go. This practice has a doc on-site 24/7. I would hold off on switching her to a doctor closer to home until we get through the dental care. They also showed me a "before and after" picture of a cat's dental care so I could see how it looks afterward. Cassie just took a big drink of water from her bowl. I'm going to pick up some baby food puree and see if she will eat that. I feel better now that she has antibiotics and fluids in her.
Also, I think I just wasn't connecting with the doctor yesterday. I heard what she said, but I didn't process it well. Today went better.

Thank you all ,
