The manager's excuses for killing cats have been repeated by the SPCA for as long as we have documented the SPCA's policies and practices, going back 50 years.

"Euthansia" does not apply to killing the healthy. This kind of killing is properly called "pest control".
An "adoption" where there is no home check is a "sale".
