Question about our rental property

So, i'm not sure if this is the right sub to post this in, but it's worth a shot. My husband and I have a house that we rent out. We have a property management company that manages it for us since we live on the other side of the country. We allow pets, and I noticed that the management company charges a non-refundable pet fee of $250 per pet. My question is who gets the money? Thanks in advance for any info!
