Which species is considered difficult to foster?

Hamsters are considered difficult to foster primarily due to their specific needs and behavior patterns. Unlike some other small mammals, hamsters are known for being solitary animals. When it comes to breeding, if a female is stressed or feels threatened, she may abandon or harm her young. Unlike species such as mice or rabbits, where cross-fostering can sometimes occur successfully, hamsters do not adapt well to being handled or raised in an environment that is not their own, making the nurturing of their young more challenging.

Additionally, the specific requirements for their nesting and care may not be easily replicated, making it harder for foster scenarios to succeed. Their nocturnal nature also complicates caring for them, as they may not be as receptive to human interaction during their active periods, which can impact their willingness to accept fostering attempts.

In contrast, species like mice and rabbits are often bred in more adaptable environments, allowing for more successful fostering under suitable conditions. Gerbils, while not as commonly fostered as mice or rabbits, also have more adaptable behaviors that may allow for successful fostering compared to hamsters.
