For shelter cats, portals open more than one door. A portal means each cat can have a bedroom/dining area separate from his bathroom. A shy cat can have a cozy bed to hide out in, with a little room left over to stretch her legs when she’s ready to explore. A stout cat can have room to stretch out in his full glory, and every cat has a better chance to stay healthy and free from upper respiratory infection. For shelter staff, it means the ability to clean and care for cats safely without removing them from their cages –and that means more time to provide enrichment, take care of customers and help every animal get out the door alive. This may explain why some shelters have reported increased adoptions of 25% or more following portalization of cages.
