Loki is a Sphynx (velvety fuzzy peach fur) and Wilson is a Cornish Rex (not hairless) and both are very warm bodied. They might be more sensible to cold but they both can keep very warm on their own (and each other)
Loki needs a little more cleaning but even that it's not really that much, a little dip in the sink every few weeks and that's it~
Lychee is the worse of all, those little white needles he wears are a pain to wash off anything D<
I'm not the best plant wise but for some reason succulent survive with me
They have almost the same care as cactis though... no ?
