Just got this reply from Whiskas
Dear Mark,
Thank you for contacting us regarding Whiskas Senior pouches.
We currently have several varieties of this product available, however, these are only within a multipack. We can completely understand your comments and fully appreciate why you would prefer to buy this product in single varieties. However, shelf space restrictions in supermarkets have resulted in both the retailers and ourselves being unable to offer this range in single varieties.
If you need any further information or advice please contact our Consumer Careline on the telephone number below and one of our Consumer Care Advisors will be more than happy to help you.
Kind regards.
Margaret Henson
