How long/ many days, weeks, or months an underweight cat would be in ideal weight when i start feeding him?? I adopt a poor cat and hes very thin. I started to feed him and i just wonder if when can he become in ideal weight?

If he is only underweight because he was malnourished (not fed enough food), then you can expect weight gain within 1-3 months. He should steadily gin weight throughout. However if there are other underlying factors such as intestinal parasites, pancreatic disease, a malabsorption problem, or even thyroid disease, then there will be little to no weight gain. It is best to have Oreo examined by a vet and at the very least have a fecal exam done to rule out intestinal parasites. You can also try giving Oreo a broad spectrum dewormer (i.e. Pyrantel palmitate, Fenbendazole) from your local pet store for prophylactic purposes. Best of luck with your new pet Oreo and I hope you can get some weight on him soon.
