Animal hoarding is keeping a higher than usual number of animals as domestic pets without ability to properly house or care for them, while at the same time denying this inability. Compulsive hoarding can be characterized as a symptom of mental disorder rather than deliberate cruelty towards animals. Hoarders are deeply attached to their pets and find it extremely difficult to let the pets go.

Feces and ammonia found in pet waste can be extremely hazardous to the health of those living in the home and needs to be properly disposed of, with a deep cleaning/sanitization and deodorizing of the residence before reentering the home.
