If you can find someone local that sells Kents products you are in business. Kent 19% rodent diet is what I swear by (at less than $16 for a 50lb bag) I have not noticed any odor issue since I switched to that. If you are pushing your females really hard you might want to go with the 23% stuff but its a dollar or two more.
