Since my kitties are having tummy problems, the vet recommended Iams Low Residue food. It has worked for 3 out of the 4. Jordan may or may not go to the vet pending the findings of his fecal sample I took in this morning. I was shocked at the cost of the food 6.5 lb bag was $30. Is there any way to get these perscription foods any cheaper and if not is there another sensitive tummy food that has worked well for others? They were on Royal Canin sensitve systems, but that may not be working (again it all depends on the results of their samples.)
