Some cats are intelligent on a different level. Every once in a while, they will do something that will just- shock you with how smart it is. Seriously, we're not kidding. We have seen cats solve puzzles that were actually meant for dogs. We have seen cats teach themselves how to use the toilet - the human toilet, that is. We have seen cats outsmart even us… in some of the funniest ways possible.
It surprises us every time. When they put their minds to something, cats really can achiever everything that they want. Age is not an obstacle, not having opposable thumbs is not an obstacle. This senior cat who just got microchipped did not like having this new tracking device inside him, and so he decided that, against all odds, he is going to get rid of that chip. And he did it. Yup. Just like that. He put his mind to something, and somehow, without anyone noticing, he figured out how to get that thing out of him.
