Animals can count?

[Catherine]

They have been doing studies and animals have a certain number sense. Not all animals and not all to the same degree, but some animals can count. I have heard this before. Some are even better at it than we are in some ways.

I will say one thing, animals had sense to stop at useful math, they had enough sense not to create algebra.

Seriously though, I have read that mice can count the number of babies they have.  I can believe that chimps are better at some things than us. Birds seem to know when they have laid enough eggs and it is time to incubate them. Now I am going to wonder and observe the animals in my life and see how they do. 

I suspect the guinea pigs would know if I shorted their vegetable count.
