- Excessive Grooming
Can be seen in many species but most commonly occurs in cats. Characterized by a loss of fur in areas of the body in which the animal has been observed to be frequently grooming (via licking). The most common areas involved are the lower part of the abdomen (belly), inside portion of rear legs and the extremities. It is critical that medical causes of hair loss (allergies, infections, external parasites) be excluded prior to making a diagnosis of Psychogenic Alopecia (Excessive Grooming).
- Wool Chewing
Seen in cats. Involves the compulsive chewing and/or sucking of fabric (including wool). Can be extensive enough to result in holes being produced in the material.
