Logically, legally and practically TNR is the only way to deal with the feral cat problem in America — 12 Comments

  1. Three years ago our colony consisted of 17 mostly unneutered cats. Today, we have 10 neutered and 1 elusive female. We lost 3 to illness and 3 to unknown causes. Kittens from the fertile female have all been homed. We continue to attempt to capture Mom.

  2. I saw cats in an area about 6 yrs ago. Alot of cats, about 50. I TNR’D them. Now this colony has less than 20. Sometimes we get a dump or 2 but if friendly we hime it and if not TNR it.

  3. My colony is stable now thanks to TNR. I started out with 19 cats. A few “disappeared” which I feel sure was due to coyotes. I was able to find homes for several more. All of the males have been neutered and I only have one female left. Five females were spayed before they could become pregnant. Imagine how many kittens those 5 females and 4 intact males could have produced if not for TNR. And I have documentation on every one of the spays and neuters as “proof.”

  4. In Julie K. Levy’s own words:

    “Virtually no information exists to support the contention that neutering is an effective long-term method for controlling free-roaming cat populations.”

    “Free-roaming cats do not appear to have sufficient territorial activity to prevent new arrivals from permanently joining colonies.”

    Levy, Julie K., David W. Gale, and Leslie A. Gale. “Evaluation of the Effect of a Long-Term Trap-Neuter-Return and Adoption Program on a Free-Roaming Cat Population.” Journal of the American Veterinary Medical Association 2003, 222(1)

    Or these comments from Julie K. Levy’s other study::

    “In both counties, results of analyses did not indicate a consistent reduction in per capita growth, the population multiplier, or the proportion of female cats that were pregnant.”

    “Implementation of the stage-structured model suggested that no plausible combinations of life history variables would likely allow for TNR to succeed in reducing population size, although neutering approximately 75% of the cats could achieve control (which is unrealistic), a value quite similar to results in the present study.”

    Levy, Julie K; “Analysis of the impact of trap-neuter-return programs on populations of feral cats”

    Pretty damning conclusion regarding the efficacy of TNR.

    “No plausible combinations…. would likely allow for TNR to succeed…”.

    In other words – it can’t work.

  5. Please provide just one example, from anywhere in the world, where TNR has ever eliminated, reduced, or even just stabilized a community’s cat-population; in any region larger than 1 single closed-system TNR colony. Just one, from anywhere on earth. We’ll wait. Even Julie K. Levy the head honcho of TNR research pleaded with the whole world last year to provide just ONE example so she could parade that in front of everyone to prove she was right. Not one person anywhere in the world could provide her with even ONE example.

    You have been practicing TNR in the UK for over 60 years now and all you’ve managed to do is more than double your stray cat populations by promoting and practicing TNR. Even your own TNR programs are a dismal failure and yet you still insist on telling everyone else that TNR works. XXXXXXXXX


    • For the reasons stated it is the only method that can be employed. That is my argument. You can search the site for instances of success stories. I have redacted parts of your comment because as usual it is gratuitously rude.
