Rosie had terrible runs, so bad We had to give up any thought of the cage, for weeks.A few weeks of chicken/ fish and rice and then prescription kibble settled Her down a bit and since then it has been trial and error re food.She had so much chicken etc She then wouldnt eat just kibble so slowly We have introduced wet food, Natures Harvest , and this seems to be ok ish.She liked Wainwrights kibble as long as it was mixed with anything home cooked, not always convenient, the wet food went straight through Her.Our vet said to keep up with the chicken/ fish for a few days then very, very slowly introduce a new food.If it reoccurs then its back to chicken etc until tum has settled then try something else.It does really seem to be trial and error and if you find something that suits stick with it as switchingfoods can upset the tum.You will get wonderful advice on here, I am still a newbie, and have found the help you get invaluable. Ps Rosie is now nearly 7 months and We still have explosions at times so havent quite cracked this food thing and contemplating trying raw food.Good luck.
