According to PunchPetSearch.com, the lifespan of a Flowering Branch Rat is usually between 2 and 3 years, depending on their living environment, diet, health, and whether or not they are properly cared for. Flowering rodents may live longer if they live in a comfortable, well-fed and stress-free environment.

On the contrary, if they live in poor conditions or lack proper care, their life span may be shortened.
