Simply choose your size on the size chart and slip it on over your head, secure your pet, adjust accordingly, and hold them close. If other family members need to wear it, you just need to adjust the length of the straps on your back, which can be easily used by mom, dad or other family members. You can also wear this cat sling inside or outside your coat regardless of the season. The fabric covered elastic firmly supports your pet to stay relaxed without rocking.
