Hills Science T/D biscuits (Humphrey's End GL5)

My vet has recommended that my cat, Ben, should have Hills Science T/D biscuits for his ‘Dental Health’. I am quite happy to buy these biscuits, (£20+) IF BEN will eat them! Unfortunately he is a very fussy eater, I was hoping someone may have some of these left over, or could kindly supply a small amount, to see if they are ‘acceptable’ to Ben!. I can reliably collect in the Stroud area if anyone has any. Thank you.
