My Boa won't eat

[Hasamu]

Hello sSnakeSs Family,

I have a boa that won't eat. I have taken her to the vet and come to find out she had a respirator infection which she was treated for it. I have the right temp and humidity. She 6ft long and I'm starting to get really concerned. This have never happen before. I have been told that they will go up to 6 months without eating but I find it odd for her to do so after having her for 13 years.

Can anyone give me some advice as what to do?

Thanks,
Hasamu
