Is my cat neutered? Can he no longer breed?

My mother made an appointment for my kitten, Jasper, to be de-clawed and neutered. However, when he came home i realized that his paws were all bloody, so he was indeed de-clawed, but he still had his testicles. My friend told me that they might have just performed a vasectomy on him, but I wasn't sure if they did that or not on cats. I would like to breed my cat later in the future, and was upset when my mother made this appointment. Is there a possibility that my cat can still breed? Please share your thoughts! Thank you!
