Trusted Housesitters, is a great option for finding house sitting jobs in London. To sign up, you must register, fill out a questionnaire to prove you’re pet-friendly, and you should usually expect to provide references. Once you’re given the thumbs up, you can reply to ads, and filter by location, duration and animal type.
You can apply for house sits in many cities round the world too. One of our Tokyo Cheapo team members uses Trusted Housesitters, and has looked after houses with cats and ferrets (separately).
