Jan one time when Sunny the cat got real sick and they told me he had to eat to get better and to give him his meds I had to use can cat food from the vets office and use a syringe to force feed him. It worked but it was messy and it took a lot out of both of us but it worked.

Ususally the first day out of surgery is the worse.

Good luck and keep us posted
