Maine Coon Exercise 

Encouraging your Maine Coon to enjoy playing and being active should start when they are still kittens. Maine Coons tend to develop into couch potatoes when they’re older, so making play a part of their routine can help them understand its importance. 

Even if you play with your Maine Coon for a few minutes a day until they get bored, it’s better than no play at all. Toys that they can bat at and chase, like automatic toys or wand toys, are suitable options, though some cats enjoy chasing after a toy once you throw it in the air. You may have to experiment before you find toys they like. 

Giving your Maine Coon a cat tree that offers big spaces to lay on will also entice them to jump and climb. A cat tree that is high up helps as these cats are very good jumpers. They should also have some scratching posts to keep their nails intact and help them exert some energy too. 

If you adopt a Maine Coon when they’re young and they’ve been vaccinated, you can consider trying to take them for a walk or for some outdoor time in your yard with a harness. Some Maine Coons will take to being outside, while others won’t like it as much. If you manage to help your Maine Coon cat enjoy walks with you, it’s good for them.
