If you also like cats, please help me, please don’t abandon your pet

I have adopted some cats in Beijing, which require a large monthly expenditure, and I want to keep them.I like cats very much, very much, and I don't want to discard them and make them one of the stray cats. I used to have only 2 cats, but after a few years, I adopted some more cats and they have reached an amazing 100. I have sterilized them.I would like to get some help. It doesn't cost you much money. You can keep 2-5 cats alive for $20 per month and keep them healthy for $50 per month
