London (BBC): Spongecake, Donut and Mocha are adventure-loving cats turned world travellers.
New Yorker Dan Nguyen started filming their urban explorations and uploading videos to the social platform TikTok.
Dan’s cats were able to travel after a long period of careful and gradual training. If you choose to travel with your pets, please consult your vet.
