Try an untame, afraid of humans roborovski escaping... Thats when we swear a lot lol
Whizz can get from one corner of the room to the opposite corner in about a second and is way too fast for us to hope to catch her until she runs into something she can't get out of. Muffin fortunately was kind enough to just go and break into the binbag we'd just put some of her cage contents and food store in so she was easily retrieved. Skip is even nicer and hasn't escaped yet
