Typical cat food palatability assessments consist of either:

Preference trials: A two-bowl trial measuring consumption when given two options. The first bowl approached, first food tasted, amount consumed, and intake ratio are used to measure preference.

Acceptance trials: A one-bowl trial that generally only measures the amount consumed.

While these common trial methods are valuable in assessing preference and palatability, AFB International sought to determine other ways to evaluate cat food enjoyment, as well as develop methods that would be representative of what pet parents might experience at home.

Trials conducted at AFB's Palatability Assessment Resource Center (PARC) found behavior methods can augment consumption data in preference and acceptance trials to provide additional insight to a cat's feeding experience.

 

FOOD FOCUS - Nose in BowlSM (NIB) Trial

Purpose: Measure cat's interest in food and help distinguish products with similar consumption

Approach: Sixteen individual cats were fed four diets over four days in acceptance trials. Video- recordings aided in using food focus to distinguish preference between diets. Food focus, defined as the time spent eating, sniffing, and engaged with their food, was quantified versus time distracted. High food focus indicated palatable food and high enjoyment. Low food focus indicated the cat was distracted while eating, which could be related to palatability.

Results: As shown in Chart 1, three diets had similar consumption, but diet A had significantly higher food focus. This indicates diet A was enjoyed more than C or D. And while diet B also had high focus, the proportion of food consumed was much less than the other diets. This could indicate the cat had difficulty biting or chewing the food, and may provide insight to pet food manufacturers on where to focus product improvements.

 

WORK EFFORT - Puzzle Trials

Purpose: Measure effort cats are willing to exert for treats, as well as mimic the effort cats are expected to 'perform' for treats at home.

Approach: Puzzles presented obstacles between the cat and treats. Sixteen individual cats were offered two puzzles, each with a different commercialized cat treat dispersed throughout. As the cat consumed treats from one puzzle (Treat A), it became more difficult to find and reach the remainder of Treat A, but easier to find and reach Treat B in the other puzzle. The trial completed when each cat consumed 50% of total treats offered. Treats consumed (Treat A vs. Treat B) were quantified and indicated preference.

Results: This measure aids in distinguishing differences between cat treats. Chart 2 illustrates that despite the cats needing to exert less effort to obtain Treat B, the cats persisted in choosing Treat A - the more palatable option.

 

INTERACTION - Hand-Feeding Trials

Purpose: Evaluate a food's ability to entice cats into the lap of their pet parent and prolong interaction after the food is gone.

Approach: Sixteen individual cats were offered, by hand, commercialized paste treats encouraging close contact during feeding. Development of enticement and interaction scales intends to interpret treat preference and enjoyment in future trials.

Preliminary Results: All treats enticed most cats to the greatest behavior measure – sitting in a technician's lap (Chart 3). The interaction scale (Chart 4) suggested the more a cat enjoyed the treat, the longer he allowed interaction (petting), even when no more food was offered. Brand C Tuna influenced cats to interact the longest, suggesting the interaction scale can differentiate products.

 

 

Conclusions

Behavior trials with kibble, dry treats and paste treats demonstrated additional ways to assess palatability and food enjoyment beyond consumption to describe an additional dimension of the cat's feeding experience.

Behavior and enjoyment data can augment consumption data to help pet food manufacturers develop products that provide more interaction between pet parents and their cats, and the assurance they are offering their cat a food they enjoy, not just eat.
