Well, he broke his good streak. Oliver pooed on the rug and I found it this morning--right in front of the boxes where he always messes. I think the reason he did it is because my barn cat Shadow, that we brought in so Oliver could have company, that has been held captive indoors for about a week now against his will, has been wanting to go outside and I haven't let him go out. Last night Shadow was ripping at a hole that Oliver made in the rug by the door, so we let him go outside at 12:00 am. We woke up to the surprise. I really think it is totally a behavior issue with Oliver and his soiling on the rug. He went about 7 days without making a mess and as soon as we let Shadow out and he was alone in the computer room for the rest of the night he pooed on the rug. I can't wait to see what the vet says about him on Weds.............
