Cat Royal Canin Veterinary Gastro (South Oxhey WD19)

Dry food for cats, about a third of a 4kg bag. Been trying to get my cat to eat this as treats on vet's recommendation but he is fussy, i.e. normal cat behaviour! He's been having it on and off mixed with other dry treats for about 18 months but he'll never get to the end of it before best before date mid December 2024. Anyone interested? Can also meet for handover around Euston some weekdays
