Identification no longer needs a collar. Microchipping is safer and more effective. For use with a magnetic cat flap? Update with the new microchip operated cat flaps – www.sureflap.co.uk and Staywell PetPorte. For treating fleas? Spot on products are safer and more effective. However, you can put a GPS unit on a collar if you want to keep track of your cat. Google for people who sell them. Just putting on a collar because it looks nice can endanger the life of your cat. Some very glamorous looking collars are downright dangerous even on a cat living indoors. Collar injuries are much rarer than road accidents but then collar-wearing cats are rarer than those without collars (Calver et al., 2013).
Collars with elastic inserts are dangerous, particularly if they are loose fitting. Cats can get their paws stuck in it or may be half hung if it catches on a branch etc or on a piece of furniture.. The elastic just doesn’t give enough if the weight is on it. During seven years one cat rescue in the UK had five cases where cats were in distress because of collars – two injured legs; one lost and emaciated; one stuck in a tree upside down, and one hanging from a low branch quite unable to extricate itself. The Mayhew Animal Home had to operate on a cat in 2015 that had got its leg stuck in a “stretch rubber” collar so long that the collar was embedded in its flesh.
Collars reduce or even stop cats killing birds and mice. But you can do other things instead. Keep your cat indoors for dawn and dusk. Careful siting of bird tables etc will also help reduce casualties – more detail here from the RSPB. Put scrunched up wire netting under shrubs if your cat is using these to ambush ground-feeding birds. Bells on collars will reduce wildlife killing but some cats learn how to stalk without activating the bell. CatAlert collar which emits a bleep when the cat pounces had a better reduction in prey than a collar with a bell or two bells (Nelson et al., 2005) but I cannot find a supplier. The Cat Bib (Calver et al., 2007) seems effective. It fits on an ordinary collar so it requires care with the collar (not the device itself). There is also the bright Birdsbesafe® collar, which looks very promising (Wilson et al., 2015).
Quick-release or snap collars are safer than elastic ones. Choose a collar in a soft material (not leather), well made, no sharp bits. Look for a quick-release buckle. Test this. If you can’t open it easily, then it is to
o stiff to be quick-release. If your cat occasionally loses its collar, then this is collar design where the quick-release buckle really works. The collar should be neither too tight nor too loose. You should be able to get one or two fingers into it.
If any reader knows of a completely safe collar to prevent bird catching please let me know. There is a useful video of how to fit a collar here.
