Thank you all for your suggestions and most of all your support and love. I'm writing this with tears flowing down my face. You all are soooo kind!!
I'm taking Benny to the vet today after work. More blood work. I tried the dog food, but he just turned up his nose. My other kitty, TC, hogged out on it.
But today, Benny ate Science Diet canned baked tuna dinner. I kinda psyched him out by using the tuna dish instead of the regular bowl. The fluids are helping. I'll keep you posted. Thanks again.
