What does tnr mean?

Tnr is a sterilization operation for stray cats and dogs.

TNR is a humane management method to replace euthanasia and reduce the number of stray dogs and cats. TNR sterilized them so that they could not reproduce. Since the late 1980s and early 1990s, several animal protection organizations have gradually promoted TNR in the United States.

There are still some unconventional methods that TNR can't accept. A study on 20 10 pointed out that the animal population that controls TNR is easily disturbed by other factors.

Actual effect of TNR:

Kathy L. conducted TNR project research in the university environment, and the results showed that the migration rate of stray animals decreased by 70% during 10, and the overall population gradually decreased to 70%. Julie K. Researchers spent 1 1 year (2002 1 month 199 1 April) on a complete population statistics of stray cats in 2002, and the total number decreased by 66%.

No newborn kittens have been observed since 1995, and TNR has also been implemented in Greece and Italy. Los Angeles treated 197 1 year/10,000 dogs. After the introduction of low-cost ligation, the number dropped to only half in 1986. During the eight years from 1976 to 1984 in Vancouver, Canada, the number of wild dogs decreased from 80,000 to less than 9,000.
