I can't help you with the pee part but, wanted to welcome you to YT!! Your furbabies are adorable!! as for him not warming up to Angel...it took Sadie a couple of weeks before she really liked her new fursister...and she will still get attitude with her from time to time...just give him time...I'm sure his little nose is out of joint right now...he is probably thinking...what the heck is going on here!!! I am the baby here!! Good luck! and
MERRY CHRISTMAS TO YOU TOO!
