[Watership Down] What does it mean when rabbits can only count to 4?

So when they see 4 items they can recognise it just fine but if a fifth one suddenly appears their brains go Error 404?

basically, their number system is one, two, three, four, lots. 

They don't distinguish between 5 and a million linguistically- if its more then four, it's just "lots".

This is actually not so far fetched as it seems- in societies like hunter gatherers where you're unlikely to have to deal with more then a handful of items or count things precisely, similar systems appear in human languages. 

It's important to note that these people (and rabbits) can distinguish between five and ten- one's a bigger pile then the other. They just don't count them as two numbers. They're just different sizes of lots.
