Police are investigating a pet grooming business in Lincoln Park after a cat owner claims her animal was abused at the shop.

Cassandra Johnson says her cat 'Roxy' was fine when she dropped it off All Petz Grooming, but when she got home the animal was barely able to walk.

"Once I got her home and opened the carrier, she came out and was limping," Johnson tells WXYZ.

The owner of All Petz Grooming denies the allegations.

"Some people like to make themselves look ugly by telling lies and trying to beat down the underdog," said John, who refused to give his last name.
