Abstract: The invention concerns a device (1) for testing sniffing of a pet, comprising a fixed casing (10) intended to be placed on the surface separately from the pet, a receptacle (2), which is rigidly attached in the first front opening (102) of the casing, an air flow sensor (3), an odor line (4), a calculator unit (6) for determination of a air flow derived databased on the air flow measured, a presence sensor (5) detecting the presence of the pet. The unit (6) is configured to command sending of the odorant stream (41) in the odor line (4) as a reaction to at least the fact that the presence sensor (5) has detected the presence of the pet.

Abstract: Refusal-based methods of establishing a cat or dog food preference, which can include methods of selecting a preferred cat or dog food among multiple foods as well as methods of determining palatability are provided. The methods can include presenting a cat or dog with one or more small samples of a test food and observing for refusal behavior, which can include refusing to eat a food sample. Higher numbers of instances of refusal of a particular food can be correlated with lower palatability.

Abstract: The presently disclosed subject matter provides refusal-based methods of establishing a cat or dog food preference, which can include methods of selecting a preferred cat or dog food among multiple foods as well as methods of determining palatability. The methods can include presenting a cat or dog with one or more small samples of a test food and observing for refusal behavior, which can include refusing to eat a food sample. Higher numbers of instances of refusal of a particular food can be correlated with lower palatability.
