Animals are part of nature, sometimes welcome in our gardens, sometimes not. Hence questions involving animals have always been part of our site, as far as they touch our everyday gardening actions.
So far, we have always looked for questions with the main focus on gardening, whether it was about welcoming and supporting animals to attract and protect them:
Bird-friendly gardens, identifying poisonous plants, attracting pollinators or beneficial insects....
Or about deterring them or protecting our plants from harm:
Keeping wild or domestic animals out or away from out gardens, protecting our plants from insects or slugs etc.
Lately, there have been a few questions about using small animals in sustainable gardening:

They ask about suitable breeds and other aspects of animal husbandry besides assuming the animals to fulfil a certain gardening tasks like, in this case, keeping grass short while staying away from certain plants. Do we see these as on topic on a site that focuses on gardening?
