The sole caretaker on the island is getting old and won't be able to look after the cats forever, so the Aoshima Cat Protection Society decided to spay/neuter the cats and let nature take its course. This is going exactly as planned. The author thinks it's sad that a popular tourist attraction will vanish soon. I can sympathize with that while still knowing it's for the best. The sad part is that the Cat Mama has to wind things down. This does not imply any kind of failure on the part of the Society.
