Cats & Dogs & Dogs & Cats

Well it's not going to be easy. We tried to get the two together last night by just opening the door between the upstairs and downstairs and letting things flow naturally. Wendy the cat was upstairs when Tink came in and she promptly went under the bed where she hid for about an hour. Tempted out by a piece of cheese she joined us downstairs because Tink was outside. Once she came back in though the cat hid behind the couch for the rest of the night until I took the dog upstairs for bed. I guess this is going to take some time. At least the cat stood her ground. They don't have to be buddies. I would just be happy with them each giving the other their space and peacefully coexisting. Is this too much to ask? I sure hope not.
