Thelma, how's everything going with your boys?? I sure hope they work this out soon. To make a loooooong story short, my husband's cat absolutely DID NOT want anything to do with my cat for the longest time when we first tried to introduce them ...but after 6 months of different tactics, he finally came to accept it. Now they are just like brothers. They do fight on occasion, but like human siblings...it happens I think what happens with my boys is they start playing...but then it gets a little rough. A few hisses are thrown out (by my husband's cat) and that's about it. Most of the time they co-habitate pretty well. I do think they are just getting used to who is "top cat" around there since they have finally settled into the new place. Do let us know what happens though! It would be nice for you to get a sound night's sleep I'm sure!! *hugs*
