Help Kovács Zsolt to Spay/Neuter CATS

Hello there!
My name is Kovács Zsolt, and I humbly ask for your help.

I'm living in a cottage outside the city, and I currently feed 30 cats, who are taken from the nearby city, because they were stray cats. I just could not overlook their suffering, so I decided to make a step and took them in.

Everything was fine until COVID hit in. I had less shifts, less money. I still managed to feed them through sacrifices, but I would like to Spay/Neuter them, since I can't afford to feed any more animals, also i'd like to evade the possibily of inbreeding. Now I'm trying to quarantine the females during those day when they are fertile, but its really hard to manage.

So again, I'd like to ask for your help, to get them neutered as fast as possible.
Thanks in advance, and thank you for reading this message of mine.
Have a nice day!
