I have a feline that isnt even a year old yet, more like 7-8months old, when i leave to spend the night with my boyfriend, my roomates lock my cat in a dark room that gets really hot (and i mean hot, even with -10 and the window cracked that room dosent cool off), with only his food water and litter, no toys or anything for him to do, he is usualy locked in this room 8-10 hours at night. can this cause serious problems with my little fur baby
