Help me keep neutering the cats in my area and to keep looking after my 55 + rescued cats.

I have rescued a lot of animals over the years and found homes for many of them. Since my last dog died I got really depressed,and felt really alone without him in my life.During the two years I spent alone,I had a lot of rescue cats handed over to me by other animal lovers that needed a home.Each one of my rescues has their story and is unique.I love them all,however the cost to look after them is immense,especially the expensive vet fees.To put cars for adoption locally is insane as most people are already looking after many qs myself and they can't be trusted as most of the animals the end up back in the street again.I am trying for years to finish my home for my cats to have a better environment with a few catteries and runways on the ceiling and in all rooms do that they can have the best possible life inside as outside can be very dangerous for then here.However,especially with the corona it has been almost impossible to save money to finish off the house and given the money I owe to the vets for neutering the strays in my area and taking whichever needed a vet to the vets has really set me back.One day I hope to be able to have that dream come true,and to also have enough to keep neutering and looking after the stray cats in my area.It costs a fortune to neuter one,especially females,and the vet fees for any issues with them are immense.I need to raise enough finds to finish off my cat rooms,their cattery,and to be able to pay off the vets and also help more strays in my area.My cats and dog are my life,I chose to spend the rest of my life looking after them and helping the strays.Thank you for the help no matter how large.
