Overview
Hill's Science Diet Adult 7+ Perfect Digestion is a senior cat food built around chicken, barley and whole oats, in a 3.5 pound bag. It's formulated with ActivBiome+ technology aimed at gut microbiome support.
This formula targets digestive regularity specifically, using pumpkin as a named ingredient alongside the microbiome focused ActivBiome+ approach, rather than being a general purpose senior food. It's also sold in 6 and 13 pound bags for owners wanting to buy larger once a cat is confirmed to do well on it.
- ActivBiome+ technology for gut support
- Formulated for cats age 7 and up
- Contains pumpkin for digestive regularity
- 3.5 lb bag, chicken barley and oats recipe
Who it's for
Owners of cats age 7 and older experiencing digestive irregularity or wanting preventive digestive support are the target. It's a limited ingredient formula rather than a food built for weight management or dental needs specifically.
Strengths and trade-offs
Drawn from this product's published specifications.
- Formulated specifically for digestive regularity
- Limited ingredient, drug free formula
- Also available in 6 and 13 lb sizes
- Senior only formula, not for younger cats
- Smaller 3.5 lb bag costs more per pound
Performance notes
ActivBiome+ is Hill's proprietary approach to feeding the gut microbiome, paired here with pumpkin, a fiber source often used to support regularity in both directions. Barley and whole oats provide the carbohydrate base rather than corn or wheat.
