What is something you wish would be invented for your pets?

Hello, I’m a high school student in STEM, currently wanting to conduct experimental research that would benefit pets and pet owners. What is something you wish would be invented for your pets that is cost-effective but has not been brought to market yet? Thank you!

A smart collar that tracks health metrics like heart rate and activity levels, and sends alerts to owners if something is off.

An automatic pet feeder that dispenses food based on the pet’s daily activity levels, helping to manage weight effectively.

A portable, self-cleaning litter box that makes it easier for cat owners to maintain hygiene without constant scooping.

A device that can detect when a pet is in distress or pain and alerts the owner, potentially preventing serious health issues.

Smart toys that engage pets mentally and physically, adapting to their play style and preferences to keep them entertained.
