Has anyone tried the Orijen biscuits ? as most of you know we had Bengly Bum problems when we got the Bengals so I try to get food that is grain free and I was reading up on the orijen and it sounds good. Mellika and Raffiki are almost ready to go onto adult but we are getting Teeko in 5 weeks (cant wait) and it might be difficult having 4 cats on adult (they have all been on kitten) and Teeko on kitten, the Orijen says that it is for all ages.
