I have a 12 month old British longhair/ Norwegian forest cat cross that has become very fussy with his food. He eats a mix of a complete dry food with a little wet food twice a day, he will now only eat Cosma Thai chicken and liver pouches along with Purina Opti-start junior in chicken (dry food). He has access to his dry food all day with wet food been given a little on a morning and the same on a night, he has now got to the age where we are trying to phase out his junior kitten biscuits and replace with an adult food. We have already tried several brands of adult food mixed in to his purina opti-start junior biscuit and he will not try them he just wants to eat the junior biscuit he has been eating since we got him. Any suggestions of a complete dry cat food that has a small kibble size that he might try to get him on to adult food?
