Hello...If you want my advice of what i know of laperms you'd be silly not to take this pusscat home..
they are wonderfully fabulous creatures and far more laid back than devons but also got their playful side but really really big cuddle monsters who get on with everything you throw at them be it kids, dogs, cats, strangers, hoovers, diy tools you name it they are phased by nothing.
i have got to know of quite a few cats swapping homes and being imported etc and every single one without exception are settled withing 48 hrs or less .
may i ask who has this laperm you are going to look at ??? If its with a breeder etc i may know of it already !!!
please get in touch with me, a few laperm breeders also have devons so may be able to help you one way or an other !
