Why? So I could keep the cat? If the only way I could have a child is
to dump the cat, then so be it.

If money is so tight that one has to make a choice between a cat and being a
parent to a human child, then that person shouldn't have adopted a cat in the
first place. Adopting a pet is a lifetime committment. It's not a thing to do
'til something better comes along. It's not a thing to do 'til a better job and
move to another location (no pets allowed) comes along.
