Hey there! You can find a link to the commercial license on the product page. Look for "Mana Seed User License" after the product description. To briefly satiate your curiosity, though: yes, you can use it for commercial projects.
I am definitely planning an update to this asset in the future. There are a few more animals I want to add, along with some more animations and color swaps. A sleeping animation is a good idea, thanks for suggestion. If you own this when the time comes, you'll get that eventual update for free 😊👍
