Apparently human scientists have managed to prove cat saliva has a mild detergent which helps clean our fur. It also contains a lot of bacteria. Bacteria is everywhere as my girl tells me. The detergent is interesting. We cats use our tongues to clean our fur and we’ve been doing it for centuries. I don’t suppose I ever questioned it before I found out what the human scientists have been up to, but it’s good to know my body is designed well. I don’t think any human gets to take credit for the cat design.
