Should I Attach a Bell to My Cat’s Collar?

Consider these pros and cons before attaching a bell to your cat’s collar.

Does your cat bring you dead animals? While this common behaviour is kind of yucky, it’s also sort of endearing – your cat is bringing you what she believes to be an excellent gift. But despite their generous intentions, hunting by domestic cats is affecting ecosystems and pushing some species to extinction. So what can you do to keep your cat from catching wildlife? There are two primary solutions to consider: keep her inside, or attach a deterrent (such as a bell) to her collar.

A closer look at the options

Of course, the easiest method of preventing your cat from killing birds and rodents is to keep her inside all the time. In the safety of your home, your feline’s exposure to prey animals will be limited to any mice that happen to get into your house. If you aren’t willing to curb your feline’s wanderlust, a common alternative is to attach a bell to her collar to alert wildlife of her approach. But is this a safe and effective option?

The pros and cons of bells

number of studies have looked at whether or not bells help prey escape from cats, and the general consensus is yes! Bells on collars seem to reduce the amount of prey caught by about half, which could be enough to no longer pose a threat to ecosystems.

Effectiveness aside, many pet parents worry that a bell will hurt their cat’s ears. According to Veterinary PhD student Rachel Malakani, a collar bell will produce sound at about 50-60 dB, but studies have shown cats to be unaffected by sounds under 80 dB. While some cats with anxiety may not react well to the bell’s sound, it’s likely that the majority of cats simply won’t care.

Some owners worry that as well as alerting prey, a bell would also alert large predators to a cat’s presence. While this is possible, given most predator’s acute hearing, it’s unlikely that the relatively quiet noise of a bell would make the difference between your cat getting detected or not. If you live in an area where your cat is at risk of being attacked by large animals you should probably be keeping your cat indoors anyway, or at least supervise their outdoor activities. You can also invest in a cat enclosure, which will allow your feline to enjoy the fresh air safely!

Bell Alternatives

If you’re unwilling to put a bell on your furry buddy, you do have another option – cat bibs. Sold under names like Birdsbesafe, these devices are brightly colored to alert potential prey to the cat’s presence before they can pounce. While your cat might look a bit silly wearing a rainbow bib, the scientific research on these products shows they reduce predation rates by roughly the same amount as bells. That said, the devices that rely on color to alert potential prey work much better on birds (who have very good color vision) than they do on small mammals (who generally have quite poor vision).

If you’re scared of attaching any collars or collar-mounted devices to your felines – you shouldn’t be. While fears that cats can become strangled or trapped by a collar caught on debris are common, actual adverse effects from collars are rare. One study looked at 107 veterinarian practices and found only one collar-related injury per every 2.3 years, with collar-related deaths being even rarer. You can mitigate your fears further by using a breakaway collar.

If your cat ventures outdoors, especially if you live in an area with endangered species, please do your part to aid conservation efforts by outfitting your kitty with an anti-hunting device.

Did You Know: A border wall between the U.S. and Mexico would cause mass ecological damage?

Article originally published here:

President Donald Trump wants to “build a wall” between the U.S. and Mexico that, depending on your political allegiances, will either keep out dangerous undocumented immigrants or will serve little purpose outside of wasting taxpayers’ money.

One potential effect not receiving much media attention, however, would be felt by plants and animals local to the areas surrounding the border.

A continuous wall on the border between Texas and its southern neighbour will require 1840 km to be built in Texasalone. Estimates for the habitat loss are approximately 12-20 hectares (30-50 acres) per kilometre of wall.

Texas is at risk of losing up to 36 800 hectares (92 000 acres) of habitats, and that’s before even accounting for the roads that will be built to construct, maintain and monitor the wall, as will facilities like guard houses and tech hubs.

But at least the organisms outside of the building zone for the wall will be ok, right?

Not quite.

A wall at the U.S./Mexican border will cause something called habitat fragmentation. This occurs when something (usually either human constructions or geological events) separates what used to be a continuous ecosystem. Habitat fragmentation, in turn, causes population fragmentation, as animals become unable to travel to access the now separate ecosystem as they used to. This can have really severe effects on flora and fauna populations. If unable to travel to find mates, animal populations become inbred and unhealthy and can die out entirely.

Some plants and animals can adapt to new habitats, or live in slightly different ones, but others have specific needs only met by specific habitats. It’s possible for ecosystems to be completely eliminated by a construction like the wall, or for animals to become separated from the habitat they need to live in. Take for example the Tamaulipan thornscrub ecosystem, found near Southern Texas rivers. Agriculture and city expansions have already eliminated much of this ecosystem, and the remaining sites are directly in the wall’s planned path. With the elimination of this ecosystem will likely come the extinction of the endangered wildflower Physaria thamnophila

The loss of one obscure wildflower may not seem like a big deal, but there are many more organisms potentially at-risk including ocelots, whiskerbushes, pygmy owls, desert bighorn sheep, jaguars, Sonoran pronghorns and javelinas.

Despite this, the construction is able to occur unhindered by environmental protections due to the REAL ID Act of 2005 that allows the secretary of Homeland Security to waive laws such as the Endangered Species Act and the Migratory Bird Treaty Act.

States near the border wall also stand to lose the millions of dollars they currently make from ecotourism areas like the Cabeza Prieta National Wildlife Refuge in Arizona. Further costs associated with the wall could come from the flooding it may cause. Such was the case after 700 miles of fencewere constructed in Arizona.

It’s hard to know for certain the effects a border wall would have on ecosystems, in part due to the difficulty in studying these areas. Researchers have reported being detained and harassed by Homeland Securityand “Minutemen civilian militias”while attempting to conduct fieldwork. However, one 2014 studyexamined an area in Arizona with border barriers and concluded that while they did affect native species, they had no effect on the movement of people across the border.

Don’t just take my word for it though. A reportdetailing the devastating environmental impacts of a border wall was published in the journal BioScience, signed by 2556 scientists from 43 countries. I think it’s fair to say that science has reached a consensus, and they’re not pro wall.
