You're speaking to Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply.
I'm sorry that your question wasn't answered in a timely manner. I believe that you're correct, Lauren. Bryson has been inappetent for at least 7 days now and while warm weather can curb appetite, crying and craving attention isn't consistent with a response to the weather. While important, Bryson's behavior isn't pathognomonic (specifically indicative) of any particular disorder. Have any other symptoms arisen? Which breed and how old is Bryson, please? Is he intact or neutered?
