Draft:Rheology of cats

Due to the structure of the bones and muscles of cats, they are very flexible. Additionally, cats have been known for filling spaces like boxes. Due to this, it cats can be considered non-Newtonian fluids.

How Cats are Flexible
Cats are able to flex and contort in many ways due to their small collar bones and their longer spines. Additionally, they tend to go into small containers like boxes due to stress. This has led many to comment on their contortion abilities and it became a sensation over the internet.

For example, the internet spoof, Bonsai Kitten joked that kittens were being grown in a jar to shape them like bonsai trees.

Rheological properties
In his 2014 paper, Marc-Antoine Fardin explains how the properties of rheology can be used to measure anything including cats. He measured and estimated such measurements as time of observation, relaxation time and Deborah numbers to conclude that cats can act like liquids at times. Other important numbers in the measurement of fluids are the Reynolds number and the Weissenberg number, for all of which if they are less than one, the object is more liquid and if it is greater than 1, it is more solid.

Non-Newtonian Fluids are fluids that have an inconsistent viscosity. This means that they act as solids under certain conditions and as liquids in others.

Awards on the Rheology of Cats
In 2017, Marc-Antoine Fardin received the Ig Nobel Prize in Physics for his study on the Rheology of cats. In his study, he proved that cats are a type of non-Newtonian fluid that could be studied using principles of rheology. The Ig Nobel Prize awards scientific discoveries that first make people think and then make them laugh.
