Neuter his AND spay yours.  It's in their best interest.

you absolutely should get them both altered.  Not only is it in your best
interest, it is in theirs.  Many cancers and behavioral issues arise from
leaving them in tact.

Knowing money is often an issue, I direct you to google.  Google your area
and low cost neuter programs.  Hopefully you'll find one in your area that
can help.

If you can't, get the male done first.  Its less expensive so you can get
his vaccines done as well, and you won't have to worry about spraying and
fighting.

However, if you let the female cat out, you are going to get kittens.
Actually, even if you don't, if you leave her in tact too long you are going
to get kittens anyway.  My sister had two in tact females with every
intention of having them altered, and they were exclusively in doors and yet
some how they found a way.

Lastly, I have to say that if money is that much of an issue, you may want
to consider what is in the best interest of the animals.  What happens if
something medical happens to them?  What if she does get pregnant and
something happens with the pregnancy and she needs emergency surgery, or if
he gets into a fight and has major wounds and needs some stitching?  Having
pets costs money beyond food.  I am loath to tell people they might consider
finding new homes for their pets, but since you do have them you are
responsible to take care of them.  You have to look in your heart and see
what is best for everyone involved.

I would say to get BOTH of them fixed !!  In future if you want more furbabies the
shelters are full of all kinds of them !!

Your best solution is to do both of 'em and split the costs down the
middle. It will show that you're responsible pet owners.
