His breeder has perservered with him for two years, was getting to the end of his tether with him and luckily for me (talk about right place at the right time) he asked if I would be willing to try. I must admit I have far less experience than his breeder but I decided it was worth a try, so after having a lesson in handling Tenko, I took him on the 45min drive home, once there I popped him into his new temporary home some 20mins later I had this absurd idea to try feeding him on defrost.........................
Tenko snatched it rolled it then left it 10mins later he ate it

,
he has since had three defrost feeds, striking straight away each time

so lucky me
although I will be offering him back to the breeder ( hope he says no )
