I have not tried BC, only RP and TMF. I can only say it is a night(mare) and day difference between the two! My yearling IJCP finally started eating TMF fuzzies, she was hooked on the nasty, stinky, feces/urine coated broken limbed and sometimes headless RP rats for whatever reason. It made me ill giving them to her but she refused to switch. I was washing the dang things and still did not feel comfortable giving them to her! TMF is just a phenomal place to deal with and I could not happier with them!
