Stable unit dose compositions with high water content are provided. Such unit dose compositions include an aqueous composition having a water activity of from about 0.60 to about 0.95 and a water-soluble container formed from a water-soluble or water-dispersible film material. In one embodiment, the aqueous composition includes water in an amount of 20% to 70% by weight, a structured surfactant system which is in the form of a lamellar structure, and a salt which promotes the formation of the lamellar structure. The surfactant system may include: (1) a linear alkylbenzene sulfonate (LAS) and/or an alcohol ethoxylsulfate (AES), (2) a non-ionic surfactant, and (3) a fatty acid. The unit dose compositions can prevent the enclosed liquid detergent composition with a high level of water content from dissolving or pre-maturely dispersing the water-soluble container due to the lamellar structure of the composition.

A remotely activated reward dispenser. The remote dispenser delivers consumable rewards in response to a trigger signal from a remote triggering device. The reward dispenser uses a two stage delivery system to prevent unintentional release of the consumable reward. A vibration stage moves a portion of the consumable reward from a reservoir to a staging platform without crushing the consumable reward. The second stage transfers the consumable reward from the staging platform to an area accessible by the animal. A vibration damping system reduces the noise generated by the reward dispenser. An adjustable transition varies the feed rate for the consumable reward.
