Approximately how many abandoned animals are killed for each dog or cat used in research?

• A. More than forty
• B. More than ten
• C. More than eighty
• D. About one hundred

Answer: (A)

The key idea here is the scale of euthanasia for abandoned animals relative to those used in research. A widely cited figure in animal welfare discussions is that for every dog or cat used in experiments, more than forty abandoned dogs or cats are euthanized in shelters. This ratio highlights a stark contrast: a large number of animals end up needing homes or face euthanasia outside of the research context, which is often used to argue for stronger adoption efforts, more humane-replacement strategies, and better animal welfare practices in society and in research settings. The other options would not align with the commonly cited benchmark, so the statement of “more than forty” best captures the usual comparison.
