Keep them SEPARATED. You can find low-cost spay/neuter clinics, but there is ussually a waiting list.. a recently neutered male can still get a female pregnant.. (he may carry sperm in his system for up to 30 days after surgury)

google "spay neuter programs" with the name of your city and state to find low-cost options in your area.
