Can you have more than four Neopets?

You can have more than four Neopets, but there are some limits:

* You can have a maximum of 20 Neopets in total. This includes your main account and any side accounts you might have.

* You can have a maximum of 4 Neopets per account.

So, you can have 4 Neopets on your main account, and then another 4 on a side account, for a total of 8 Neopets. You can keep adding side accounts to reach the limit of 20 Neopets.
