It is not safe for cats to not eat for a week. Please speak with your veterinarian today about what you should do. Depending on what his urinalysis looked like, you may be able to stop the antibiotics (which can cause nausea and a decrease in appetite). You may also be able to try canned food or a different type of prescription diet food. Regardless, it is more important to get James Bond to eat regardless of what he eats right now in order to prevent potential liver problems from not eating. If blood work has not been checked, that may need to be done as well. If James Bond continues to not eat, he will likely need to be hospitalized. Good luck! I hope that was helpful and that James Bond feels better soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
