Latest Annual Report

23 January 2020 - Otto and Harrie move

Submitted by: Ben

IOSF's charismatic duo, Otto and Harrie, have moved from their inside enclosure to their outside pen. They are currently in a smaller pen with access to an inside sleeping box. As they continue to grow they will allowed into a larger area with a large pool for their use.

The two otters continue to eat well and are, as you can see, healthy and growing!

The video below shows how after being separated for 15 minutes they were happy to be reunited!

What you do is entirely up to you and anyone can take part. Whether you post on social media to raise awareness linking to IOSF's social media pages, run an education event showcasing the amazing species near where you live or decide to run a fundraiser to support otter conservation - the choice is yours!

Last year we had events all over the world, in over 30 countries, and this year we want to make it bigger again!

As usual, we have a World Otter Day map showing all the awesome events going on around the globe. Simply click on each otter to find out where and what is happening.

07 January 2020 - Harrie and Otto

Submitted by: Grace

Yesterday we introduced Harrie and Otto to each other. As usual Otto just disappeared under the blanket! Harrie just sat there quietly waiting. There was no noise from either of them so we left them for a little while to get used to each other. When we went back both were under the blanket and we could hear them squeaking to each other.

This morning all the fish had gone and there was more squeaking under the blanket.

Unfortunately we haven't managed to get any photos yet as we don't want to disturb them any more. Hopefully we'll be able to post some soon.
