Sorry, my dog has done that exact thing. Well, except for the soda part and the sandwich was at "dog level" on a coffee table. However, the cat tries to drink out of your glass if its anywhere near her. If you open a can of tuna, the cat and dog beg next to each other in the kitchen. They pretty much peacefully coexist, but when it comes to food they are really on the same page. I came home once and the dog and cat were nowhere to be found. I went down to the lower level of the house and found them working as a "hunter-killer" team with a mouse they had cornered. The cat was on one side and the dog on the other. It was hilarious. I put the mouse in a box and let it go outside. You should have seen the disapointed look on their faces.
