  1. Nice idea and I see this exists, with settings for multiple animals including:

    Cat Vision
    Dog Vision
    Snake Vision
    Bird Vision
    Horse Vision
    Honey Bee Vision
    Shark Vision

  2. There’s an app for that. Gets good reviews in general. Just for dogs though. It needs a setting for other animals tbh.

  3. This would be great, we forget that dogs see less colors than we do and that affects their performance when requested to do our tasks.
