I am no expert, Sallyanne. Obviously, my two will never be friends. But, I would give them more time and pretend everything is normal, giving each of them their own time with you, but otherwise, just let them get used to each other. I daresay that Ti will NOT live out his life under the dresser! LOL!!!! It's easy for me to say, since I'm not going through it, huh? Time is probably what he needs most. Good luck!!
