Are my hamsters hibernating?

[Lynternette]

I'm so sorry. I just can't believe what's happened.

I'm very sorry, its so unfortunate
Its not unheard of for cage mates to pass away close together, especially if its due to an underlying illness they both share.
But like you said it seems so sudden, hibernation is a possibility and since in a domestic environment they aren't designed to hibernate, they could have passed away.

I'm so sorry, poor little angles . It could have been a few things, and the vet may not be able to give you a definitive answer. The temperature could have played a part, but it is unusual for a pair of robos snuggled in a nest in get that cold. Whatever the cause, I'm really sorry for your loss xx
