been doing my research as getting our first rats in the next week or so and from what i have read so far is that i should have a tub/litter tray of soil available for them to dig in - maybe grow grass in and hide treats in.
do you do this? if so, is it better to have a small version in the cage or a bigger one outside the cage for them to use?
is this a necessity?
what else is defo needed for my rats' cage? its a furplast Jenny so plenty of space to fill with stuff!
