Whenever I was/am watching a Doctor Who episode that featured David Tennant as The Doctor, Marley would not be in the same room. In fact, the moment he heard the opening credits, Marley would jump behind whatever piece of furniture he could find that was between him and the television, and then make a mad dash for freedom.
Now, when Doctor Who comes on and it's Matt Smith, he seems to hang out in the kitchen for a bit, and then join me on the lounge and watches with me.
What an odd animal. (In his favour though, he doesn't self-mutilate of huff cleaning products like my other cat, so his dislike of a particular version of The Doctor is relatively normal.)
