I’ve recently been collecting evidence that suggests that we could increase adoption rates by incorporating more group housing into shelters. In building my study, I’m now interested in what factors make cats less desirable at shelters so that potentially we could market less desirable cats by placing them in housing that will make them more desirable. Lepper et. al (2002) examined just that, in a study with over 4000 cats they examined multiple variables in order to determine certain predictors of adoption. They also examined dogs, but I’ll just be discussing the cats today. Check out the article for yourself if you are interested in the dog analysis.

It has been shown that there is a clear correlation with fearful behaviors and euthanasia (Gourkow and Fraser, 2006), therefore we should be doing everything we can to reduce fearful behaviors. I’ve suggested that when we are forced to make euthanasia decisions based on space,  we need to take temperament into account to evaluate the potential for adoption.

Among other variables however, this study illuminates factors outside the control of behavior modification that may

influence adopt-ability. Comparing coat color, the authors chose to set tabby cats as the standard, and were able to determine that white, color point, and grey cats were the most likely to be adopted. Brown and Black were the least likely, a fact that any former shelter employee wouldn’t be surprised to hear.

Cats’ whose color or features could be attributed to a specific breed (such as Persians) were in high demand. This study found that coat length did not have an effect on adoption rates, but other researchers have found that more than half of adopters list coat length as an important factor in their selection. Interestingly, Siamese cats  had no higher rate of adoption than other cats in the study.

To me, this information says that we could easily be selecting animals that are potentially less desirable, and placing them in the front or lobby areas of shelters in group settings, and keeping kittens and more desirable animals in less prominent housing. This simple management change could potentially increase adoption rates overall, and of course reduce euthanasia rates, the goal of any shelter.
