If you have one, two, or three feral cats, and have the money to do it, you may choose to be a responsible caregiver by getting them neutered. When they weigh 2-3 pounds, most of the low cost vets will do that neuter. I know of a couple of vets that do it rather inexpensively. If you know of others, please let me know.
Dehart Mobile Clinic: They do neuter feral cats. Make sure you check their schedule of where they are going and then call them for an appointment: –> Dehart Mobile Clinic Neuter – if you want the ear tipped, you must request it.
Texas Litter Control: They have a clinic in Humble Texas and they do neuter Feral Cats. –> Community Cat/Feral Cat Pricing – They will tip the ears of the cat.
