When it comes to strong friendships, some things never change! But when a litter comes around that's better for us and the planet, change can be a good thing! My friends and I switched to @Catalyst Pet Natural Litter - a completely sustainable, high performance litter - a couple months back, and we couldn't be happier. It's better for us, and for the planet. Now that's a change we can get behind!Make the change for you and your friends by picking up a bag of Catalyst at PetSmart or Petco.com! And celebrate your friends today and always! #InternationalFriendshipDay#catsofinstagram #adoptacat #adoptdontshop #sustainability #catalyst #catalystpet #catalystlitter #changeyourplanet #saveyourplanet #zerowasteliving #naturalcatlitter #catlitter #friendship #friends #celebratefriendship #ad
