Senior food v standard food

[Dilbertian]

10yo dcat seems to like Waitrose Senior cat food in jelly the best. The sachets are twice the price of tins, plus it seems environmentally wasteful to open 4-5 sachets every day, rather than one recyclable tin.

But Waitrose only do standard cat food in tins, not the Senior food. What's the difference? Is it something I can add to standard food?

The co op recycle the pet food sachets

No clue about the food differences though-sorry!
