Personally, I am a dog person. I don’t like cats very much, but I have to recognize that cats a very interesting creatures. Their unique way of behaving is making a revolution in internet with great grumpy cat memes that people are sharing on their Facebook wall. On the web site complex, they have a gallery with over 40 pictures of grumpy and angry cat memes that will make you laugh. If you have a cat, you will probably relate to this post a lot.
