I'm planning to get 2/3 gerbils and have never owned them before. I've done a lot of reading and they seem a good option as they are awake some of the day and not too nippy.
I'm looking for some tips about where to buy a decent sized gerbilarium as the options seem to be more limited than for gerbil cages.
I was also wondering about the substrate. Would carefresh mixed with Timothy hay be suitable?
Thanks!
