I bought a djungarian hamster as a gift for a relative's daughter, but now she says she doesn't want to keep it, because it's very aggressive and always bites. She's had a few hamsters before and says this one is a true nightmare. She's been having it since a month ago and the hamster is now two-months old.
Our attempts to find a new owner have been fruitless. We called a few pet shops and offered our hamster for free, but the answer has always been no. We tried to find a new owner for this hamster online, but no one was interested. And, unfortunately, there are no pet shelters here, at least those accepting hamsters.
I can't really afford spending more time and effort trying to find a new owner for the hamster, so there seems to be no other choice but to release the hamster.
So my question is: Where should I release the hamster to maximize its chance of survival?
The location is Moscow, Russia, and the options include urban streets and parks as well as countryside forests, swamps, and fields. The current temperature is 8°C.
