Prayers for Cathy!
Years ago the vet told me cats have to eat all the time; 3 days of not eating could cause death. The vet had special medication made up to give her and I had to feed her by putting cat food on my finger and letting her lick it off several times a day. She survived and is still with me today. Even if she vomits, she will get a small amount of food
The vet is no longer alive. I cannot remember the medication given her — I think it was an antibiotic for humans made special for her in a pharmacy that does only that type of prescription.
That’s all I can remember.
