Hi! Welcome to The Den.
If you're under 18 and love animals this is the place for you.
Here you’ll find info on our two junior memberships and lots of fun things to do.
There are games, pictures, stories and loads of animal fun. There’s also information about the RSPCA and, of course, animals!
We hope you have a great time, and if you have any questions or comments feel free to send us an e-mail.
If you're a Blue Peter fan, you'll know that Mabel the dog is retiring from the show after a whopping 14 years.
But did you know that Mabel was rescued by the RSPCA and is the first ever rescue dog to appear regularly on the programme?
Why not say your goodbyes by sending in your poems, pictures and letters for Mabel. You can also post your goodbye messages online.
Find out more on Mabel's profile page on the CBBC website.
And don't miss Mabel's final Blue Peter appearance on Tuesday, 30 March at 4:35pm on BBC One.
