Question: what des the cat have to do with science

The cat is pooping! This is very important to my work.

My work is all about the bacteria in your gut; what they do in there, how they do it, and whether it can affect your physical or mental health. The easiest way to get gut bacteria to study is to wait for them to come out in a person’s or animal’s poop. It’s difficult, dangerous, and to be honest more than a little impolite to just stick a spoon up there and scoop them out, the ethics board would kick me out of the lab for good 🙂

Also I used a picture of a cat because I couldn’t find any good ones of a mouse using the toilet. The internet is strangely deficient in some areas 🙁
