Two kittens adopted during lockdown turned a mouse-free house into a hunting ground by repeatedly bringing live prey indoors. Mimi and Ruben, tabby twins, developed a speciality in catching wood mice from nearby woods and releasing them inside their owners' home, apparently treating the rodents as playthings rather than food. The cats would guard gaps in skirting boards and under cupboards, making distinctive "prittering" sounds to announce their catches. Their owners responded by chasing down the mice with upturned Tupperware boxes and releasing captured rodents back into the woods while locking the cats inside to prevent them tracking the releases. Some mice escaped into the house's fabric despite these efforts. The Guardian describes the situation as "a cat-and-mouse story in which the cats are the real pests."
