Hi, again and thanks so much for your very helpful reply.
At first you said she 'has a big belly,' then you said 'she has two lumps in it and they are soft.' The fact that she didn't show a pain response when you touched them, is good.
A bloated belly can be the sign of many ailments. The first and most important, is Feline Infectious Peritonitis or FIP. Read more, here:
Bringing her to a vet in your new area, tomorrow morning, is the best thing you can do for her. If her belly is bloated and the vet suspects FIP, s/he will will withdraw some fluid from her abdomen with a very fine needle, to see the color and consistency.
The vet will also feel the lumps you felt and try to determine what they are. They may be cysts or tumors and some imaging may be necessary, like an x-ray or ultrasound to make a definite diagnosis.
She may have some stool stuck in her intestines or a hairball. You said you feel she's been losing weight. Older cats tend to lose weight for no reason at all, but she's not all that old. Eating normally, or more than usual, plus losing weight, is a symptom of hyperthyroidism, so the vet should do a routine senior blood panel, including a Free T4 thyroid test, to get more information.
As long as she doesn't seem uncomfortable or in distress, you can wait until tomorrow morning. If her situation changes for the worse, through the night, you'll have to bring her to an ER vet center. If you don't know where one is, plug your zipcode into this site and you'll find the nearest one:
I hope all will be well with Zoe and please let me know how she's doing and what the vet's findings are. Thanks!
