Furry and fun, cute and curious, Little Mouse loves to adventure beyond the cozy burrow he shares with his family in Tammy McDoodle’s backyard.

Tammy is a sweet little girl loves doing yoga with her mom and learning new things. What Tammy doesn’t know is that her fluffy cat, Mr. Opus, and his best friend, Little Mouse, are always following along!

Lovable, lazy, and wise Mr. Opus can be found napping or trying to help Little Mouse solve problems  and  stay out of trouble!
