First of all, I do have an appointment with the vet this month. I explained the situation and her vet has not deemed it an emergency so we'll see him on the 19th. But I want to do what I can to try and help her now.
In the last months or so Sarge has slowly ate less and less of her normal food, she's been on Roudybush her whole life (9 yrs). It's got to the point she really only nibbles on it and had definitely lost weight because of it. All other behavior is relatively normal given it's hormone season. That said, she still has an appetite, she regularly demands treats and snacks and devours them happily. So I don't think it's illness.
I've tried withholding treats or reducing them (it's mostly Nutri-berries which I make her forage for, occasionally some almonds) and it doesn't help, she just screams and cries more. Recently I ordered Harrison's large food and gave them as new treats. She was excited at first but lost interest in a few days, I think it's just too hard for her. I caught her trying to dunk it in water, it didn't seem to satisfy her.
Has this happened to anyone else? Is there another yummy food that I can offer as treats, basically to trick her into healthy food? Something that comes in a big size.
