Elimination behavior patterns of domestic cats (Felis catus) with and without elimination behavior problems.

OBJECTIVE
To investigate the relationship of litter box location as it relates to cats' use of space in the house, elimination problems, and certain behaviors associated with elimination.


SAMPLE POPULATION
40 cats in single-cat house-holds with or without elimination behavior problems (20 cats/group).


PROCEDURES
Camcorders were used to record the cats' behaviors at the litter box and other areas in which they eliminated during a 72-hour period. Use of space in the house was recorded by direct observation during 400 minutes of the 72-hour period. Elimination behaviors and other cat- and litter box-associated variables were compared between groups; litter box location with respect to inappropriate elimination was assessed.


RESULTS
Litter box location did not differ between cats with and without elimination behavior problems. An inverse correlation was found between time spent sniffing and the distance of the litter box from the central core area. Cats with elimination problems spent significantly less time digging at the litter box than cats without elimination problems. There was no significant difference in the time spent pawing in litter box, sniffing, or covering excreta after elimination between the 2 groups of cats.


CONCLUSIONS AND CLINICAL RELEVANCE
Times spent digging in litter boxes by cats with and without elimination problems have been determined, and data suggest that actual digging times could be used as a means to test for litter preference and litter aversion. This information may also be used to identify cats with litter aversion prior to the development of an elimination problem.
