Product Changes Notice :      Hill's Science Diet - Specialty/Care Range Dry Food 

From October 2025  this product is transitioning as part of updates  to select products in the Hill's Science Diet range of Specialty/Care based dry foods.  There are minor ingredient changes, and some products will have changes to the shape and/or size of the kibble.  

Hill's Science Diet Adult 7+ Hairball Control Senior Dry Cat Food- EST. Transitioning from February 2026
This product is undergoing a packaging, kibble change and minor formulation update.  During this transition time, you might receive either the original or the new version in your order.

What's Changed:  Real chicken remains the #1 ingredient! The recipe has received a refresh—introducing gentle, easily digestible cracked pearled barley and pea protein, while streamlining the recipe by removing fruit and vegetable extracts. There are no changes to the overall flavour profile or feeding performance.

Feeding Transition Recommendation:
While changes are minor, some cats may be more sensitive to subtle formulation changes or texture differences.  A gradual 7-10 day transition helps selective eaters adjust and helps prevent potential digestive upsets. Read our guide on how to transition your pet to a new food smoothly here

Spot the New Look: The new packaging features subtle changes. The new version has no kibble/biscuit image on the front of the bag, and the back of the new pack has an image displaying a food bowl and ingredients. 

This page has been updated to reflect the NEW formula, but the original ingredients are listed for reference. 
For any questions regarding this update or our current stock status, please contact the Petdirect Customer Care team.

    Posted byJo-Anneon23rd Jun 2024

    I have a fussy cat, and these biscuits are now her favourite. I'm feeding her two different Hill's biscuits, and she waits for me to put these ones in her bowl, and leaves the other biscuits in her bowl.
