Penelope isn't eating :(

[Trollbie]

It's gonna be 2 months soon that Penelope (Red Milksnake) hasn't eaten... She ate a mouse pinky once within these almost 2 months but that's it. My dad even tried live but she wasn't interested at all. Since I weighed her like 4 months ago she lost 5 grams, but from my understanding that's not alarming yet?

She's active, still urinates, and seems healthy. I know snakes do this sometimes but I'm still worried. I'm out of the country at the moment and will not return till the end of this month, but I should probably plan a vet visit as soon as I get back. Till then my dad is keeping an eye on her.

ANything I should try doing? And if I take her to the vet, what should I take if she's not pooping since she's not eating? Is a urate sample enough?
