@LionTamerX,
Spay and neutering did not aid me greatly when a mother cat with four kittens all in bad shape show up at my doorstep asking for help.
Before this event I was down to three older cats and very happy to be so.
Ended up with five indoor cats now the three that I started with and the mother cat and one of the kittens.
Thank god I was able to find what I hope are good homes for the other three kittens.
The one kitten who I ended up with needed human hand feeding and I bond with her damn it beyond my ability to give up.
