Hey Packy, that sounds like the deal of the century! I remember a few cats ago when we adopted two cats from the local humane society. This was in 1992, and the adoption fee was $35.00 per cat. I couldn't believe what a crazy world it was, that we could get these incredible guys for so little money. It seems like cats should cost thousands of dollars, because they are so wonderful. Adoption fees were up to about $125.00 the last time we adopted (2013), which is still amazingly inexpensive to me. We do adopt adult cats, so the fee tends to be less, but still.
Enjoy your new family
