Dr. Marty: My Cat Cleopatra Has been with me for 12 years she is the love of my life, But she will not eat the same thing more than once, what can I do I have boxes of dry food she will not touch after one meal or well wet food I buy well known brands but she will eat only one flavor and I have to throw out perfectly good food she wont touch it a second time, it must be something differrent or she will tap me with her paw  on my hand or foot intil I provide a different menu. What can I do??? please help I cant afford such a variety of food and throw it out after just one meal.
