Hi, Clarebear -- I wish my cat Mr. Fluffy was a gentleman, but he has no use for any human -- except me -- or for any other animals, unless it is a bird (nicely stuffed and roasted to a turn). Since my last post, I have tried Dixieland Dancer's helpful suggestions and THEY ARE WORKING! "Poor Blondie" doesn't get the insides knocked out of him any more. Tuco merely lunges in Blondie's direction, gives a little growl and that's that. Blondie has learned to back off, drop what he has in his mouth, or go belly up. End of conflict. I found that so long as I am consistent, each animal knows what is expected of him/her. Also, I took Tuco for a "test drive" in the car two days ago and he did not mark, or pee, or whatever he was doing. Thank goodness that's improved! Now, if I can just get Fluffy to stop pushing the dogs around . . .
