First case found in female mountain lion in Colorado last May
The American Veterinary Medical Association said symptoms to watch for include a staggering gait, the inability to retract claws, extreme sensitivity to touch, tremors, and seizures. The illness usually lasts for a few days to a few weeks, but can also linger for more than a year.
Agreed. If you have a human, don't let them build suburbs unless you hate ecosystems.
However, humans do observably seem to hate (or at least thoroughly ignore the needs of )ecosystems enough to ruin them, so I'm not sure enough people will listen.
It's not an either/or thing. Outdoor cats are causing an ecological disaster when it comes to birds. The big solution is to spay and neuter as many as possible, especially pets. Even indoor ones can escape.
The added benefit is that when there are few enough cats that there are loving homes for most of them, then the percentage of kitties with humans to take care of them increases drastically.
Then support your local trap/spay/neuter charities. This is a miserable and painful way for them to die and likely wouldn't kill enough of them to get the effect you're hoping for. All you're wishing for here is needless suffering.
I am aware of how damaging cats are to the ecosystem, but regardless of that, I don't understand how you can live every day worrying whether the cat will come back or bring some kind of disease home with it. With our indoor cats I have control over what they eat and at most every few years they catch a cold. But nothing serious after 9 years of having indoor cats.
