Midnight not eating today. Stool is both firm and a little lose all at once. Meows in pain when walks. Very slow walking. Started today. Two instances of vomit. Looks like undigested food. I changed to cheaper food a week ago. Other cat on home is fine.

Poor Midnight! It could be the change in diet is the cause of her vomiting and stool problems. He could also be suffering from pancreatitis or a foreign body causing the vomiting, stool problems, and pain. Given that his symptoms started today, I can give you a home remedy to see if that helps. I recommend withholding food for 12-24 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet (the old food you were feeding him, not the cheaper food). If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Good luck, I hope this helps!
