If you are thinking of using Orijen why not try your cat on Applaws dry. It is like Orijen but better. It contains no cereals just 80% pure English bread chickens with 20% vegetables and natural extracts such as cranberry, citrus & rosmary extracts instead of any nasty presevatives. It contains Yucca which naturaly reduces the odour of the cats urine. Salmon oil which is rich in Omega 3 & 6 and a special blend of natural plant fibres to help reduce the build up of fur balls. My cat loves it and she is 18 years old. If you telephone them they will even send you out a free sample Freephone: 0800 083 0599
