Pound Seizure is immoral & even downright cruel for many
reasons.The Humane Society Of the United States opposes it
as do many other organizations who are trying to get this practice
banned in all states in the U. S.

Quote:

Rationale Flawed
Pound seizure proponents rationalize that animals in the shelter are going to die anyway. After all, the argument goes, the animals were lost or abandoned as unwanted pets. Why not use them for research? Many humane organizations reject this argument, insisting that animals have a right to a safe and happy existence. Furthermore, the animals chosen for the laboratory are the ones most likely to be adopted - young, one to three years of age, healthy, friendly, and of medium size. Those who are rejected by researchers are the animals least likely to find adoptive homes.

Interestingly, the National Institutes of Health, the largest funded of biomedical research in this country, stopped using shelter animals in its own in-house research several years ago because they consider such animals unsuitable research subjects. Shelter animals are not fully known by the researcher as are purpose-bred animals. Nothing is known about the shelter animals' origins, health conditions, or age, and typically the animals lack conditioning for research. Further, it is more expensive to buy, treat, and condition shelter animals than it is to purchase animals purposely bred for research. (end quote)
