Rolling Cat Feeder with Arcuate Prey Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Indoor cats lack mental and physical stimulation due to deprivation of natural hunting behavior, leading to health and behavioral issues such as obesity and undesirable behaviors like scratching furniture and eliminating outside the litter box.
Innovation Solution
A feeding system comprising hollow containers with arcuate external surfaces resembling prey, which roll and automatically dispense dry cat food when played with, providing multiple feeding devices placed throughout the cat's environment to simulate hunting and satisfy daily food rations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dry cat food is provided in a traditional bowl, then the cat's nutritional needs are satisfied, but the cat lacks mental and physical stimulation and cannot express natural hunting behavior
Solution Approach 1:
The feeding device is designed with an arcuate external surface that enables it to roll when played with by the cat. This dynamic movement transforms the static food bowl into an interactive toy that simulates prey movement, allowing the cat to express natural hunting instincts while accessing food.
Solution Approach 2:
The device automatically dispenses food as the cat plays with it, eliminating the need for human intervention during the feeding process. The cat itself operates the mechanism by rolling and playing with the device, thereby serving its own feeding needs while engaging in hunting-like behavior.
2Object-affected harmful factors
If indoor cats are kept in a safe environment, then their physical safety is protected, but they suffer from deprivation of natural outlets for predatory instincts leading to undesirable behaviors
Solution Approach 1:
The invention converts the cat's natural predatory instincts and energy, which could otherwise manifest as destructive behaviors, into a beneficial activity. By designing the feeding device to resemble prey and require hunting-like interactions, the cat's instinctual behaviors are redirected toward a constructive purpose: obtaining food in a natural manner.
Solution Approach 2:
The rolling mechanism created by the arcuate surface provides dynamic movement that simulates prey behavior. This movement engages the cat's predatory instincts and provides both mental stimulation and physical exercise, preventing the development of undesirable static behaviors.
3Adaptability or versatility
If multiple feeding devices are placed throughout the cat's environment, then the cat receives mental and physical stimulation by hunting for food, but the system complexity increases
Solution Approach 1:
The total daily food ration is divided into multiple portions, with each portion placed in a separate feeding device. This segmentation allows the cat to hunt for food multiple times throughout the day, providing repeated mental and physical stimulation while distributing the food delivery over time.
Solution Approach 2:
Each feeding device is a self-contained unit that combines food storage, dispensing mechanism, and toy functionality. This multi-functionality means that while multiple devices are used, each unit remains simple and identical, reducing the complexity of individual components even though the overall system includes multiple units.

AI summary
A feeding system and methods for feeding cats is disclosed. The system includes a package holding plural feeding devices. Each feeding device is made up of a hollow container configured to dispense a portion of the daily ration of a cat's dry cat food therefrom. Each feeding device has an internal cavity bounded by an arcuate external surface that provides the appearance of a creature that constitutes prey of a feral cat. The container has an outlet port configured to enable a portion of the cat food to gradually exit from outlet port when the container is rolled on a surface by the cat playing with the feeding device. The feeding system may include a plurality of feeding devices packaged together.
