Hello,
I’m so sorry to hear about your cat.
I’m also sorry but there is not enough information here to allow for an accurate diagnosis and therefore an appropriate treatment plan.
I recommend that you call the vet back and ask for help on a budget. See if you can drop off a fecal sample without the exam. See if they will allow you to do some diagnostics with a minimum database so that you can get help for your cat. There is a big push in vetmed right now to allow affordable care. Remind them of this. Put us all in writing and plea for your cat to get help. You she already been seen and they already have an established relationship with you. This will help you get care and it is a great case for what the profession is already being challenged with.
I will add the links below for the public press releases stating that we know too many people are struggling to find affordable access to care. I recommend you use your personal experience as an example and start advocating for help yourself. Or you can try to find a shelter or rescue that has a vet on duty who might be willing to help.
Please keep me posted.
Good luck.
Krista
Often reaching out to your local shelters and rescues is a great place to start as cat rescues see rescues with polyps and have navigated local vets who are affordable for treatment. Best of luck!
