All 4 of my cats were homeless I took in, 2 were feral cats. The first thing I do when I find a stray is take it to the Vet., Have it tested for feline luekemmia,start shots, set up time to get them neutered - all strays I have taken in are males. They all are house cats and only see the outside through the windows.
Good for you to take in strays. I hope you can get them fixed also. The only thing that will stop the strays.
I am glad you got the job, place to live and money. Good luck.
