Taken directly from page 118 of The People’s Manifesto for Wildlife by Chris Packham et al. concerning cats and wildlife:
“According to research our cats kill 55 million songbirds every year in the UK and predate a total of 220 million other animals, including mammals, reptiles, amphibians and insects.1 Given the great pressures this wildlife is under elsewhere these losses are almost certainly now significant.
It’s not the cat’s fault! And there are easy steps to take to reduce this toll.
We must ask cat owners to take responsibility, and here’s how…
- Keep cats in at night – this can reduce overall predation by up to 50%. Unless you plan to breed your pets, have them neutered.
- Ideally all free-roaming cats should be fitted with a collar and bell. This can reduce bird predation by 50%.2,3 That’s 27 million more birds in our gardens every year.”
Orchard Park Wildlife Project has recorded 27 species of birds in OP, and we also have Viviparous Lizards (Zootoca vivipara). Any of these could be negatively affected by cats.
When studying in NZ ten years ago, and co producing a blog on the wildlife of Dunedin’s Town Belt, Jill and I met with Yolanda Van Heezik, author of one of papers cited above, several times. Jill wrote a couple of blog posts about Yolanda’s research on the cat predation in NZ: More from “Project C.A.T.” (C.A.T. stands for Cats Around Town) and Where does Fluffy go? but the findings are just as relevant here.
Cats and Bats
As well as many birds, and lizards, we also have Common Pipistrelle (Pipistrellus pipistrellus) bats, and quite possibly Soprano Pipistrelle (Pipistrellus pygmaeus), foraging in Orchard Park. Cats are one of the most common causes of bat casualties.
From the Bat Conservation Trust
“Bats do have other natural predators (such as birds of prey) but cats, particularly, will learn the location of the bat roost and catch bats as they emerge.
If a bat has been caught by a cat it will almost certainly be injured. Even if you cannot see any obvious injuries there is a great risk of internal infection from the cat’s saliva.
Any bats caught by cats will need the experienced help of a bat carer.
Please follow this link for instructions on how to contain the bat and call the
Bat Helpline 0345 1300 228.
By following a few simple steps responsible cat owners can stop bats being harmed:
- Bring your cat indoors half an hour before sunset and keep it in all night when bats are most active (April –October).
- If you cannot keep your cat in all night, bring it in half an hour before sunset and keep it in for an hour after sunset.
- It is very important to keep cats indoors at night from mid-June until the end of August because bats will be looking after their babies.”
