This is a thought. It might be unworkable and impractical. We know that domestic cats have preferences in relation to other cats. They can strike up friendships. There is no guarantee that a cat will like another but it does happen and when it does their lives are improved. There must be countless cat couples dotted around the United States cosying up to each other in blissful contentment.
Would it not be possible for shelters to assign a room and a person to checking the compatibility of cats as companions? We know that shelter cats are normally keep in separate cages but some of these cats might be able to make friends with another cat at the shelter.
If it was feasible to match up cats from time to time they could be adopted out as a pair of cats. This would be advantageous from two standpoints (a) the shelter adopts out two cats rather than one and (b) some adopters will like to adopt two cats who have already made friends. It might suit the adopter.
We know how problematic it can be to introduce a newcomer to a resident cat or cats. It might not work. If an adopter can adopt two cats in an established friendship they have resolved the problem beforehand.
This proposal might not be feasible from the standpoint of resources. It would need shelter workers to be involved in pairing up cats and a room or space where the assessment could take place. However, of it could be made to work there would be significant advantages in saving cats’ lives and improving the lives of cats.
