Weird fellas, arent they lol. I honestly think he was just doing it for attention cuz i had seen him do it before and i would always shoo him off or spray him lol. And i had him out earlier today, letten him free range and gave him a shower and been given him alot of attention. Then i went to work for 7 hours and he ran up to the door as soon as i got back, changed to a really pretty color, kept tryen to climb out. Idk it might be sumthin else, thats just my hypothesis.
