The UK is dwelling to round 10.8 million owned pet cats. However the variety of unowned cats dwelling on the streets within the UK has remained largely unknown – till now.
Our new analysis, revealed within the journal Scientific Studies, sheds some gentle on the dimensions of this weak feline group. We’ve estimated there are 247,429 unowned cats throughout all city areas of the UK.
Our determine is predicated on information collected from 5 city cities and cities within the UK – Beeston, Bradford, Bulwell, Dunstable and Houghton Regis, and Everton – after which extrapolated. We selected these areas as we suspected they represented a spectrum of unowned cat density, together with excessive density and low density areas.
We used data collected as a part of Cat Watch, a group venture arrange by the UK’s feline welfare charity Cats Safety. Cat Watch inspired residents to report sightings of unowned cats, initially throughout door-to-door surveys, after which via an app, social media, and on to the Cat Watch workforce. The workforce labored to confirm the data residents offered, leading to 601 confirmed sightings of unowned cats.
There are a couple of challenges with reporting unowned cats, equivalent to the very fact owned and unowned cats can look the identical. So observers could incorrectly establish an owned cat as an unowned cat, or vice versa. There may also be underreporting (as a result of not all unowned cats will essentially be seen), and a number of stories of the identical cat. To account for these potential errors, we developed one thing referred to as an built-in abundance mannequin, which mixed the data from residents with confirmed sightings verified by the group workforce.

In our 5 examine areas, we discovered two elements had a major affiliation with unowned cats in the neighborhood. In areas with higher socioeconomic deprivation and better inhabitants density, there tended to be extra unowned cats. We utilized these findings to the remainder of the UK’s cities and cities utilizing official inhabitants statistics and socioeconomic information. We calculated the common density of unowned cats throughout city areas within the UK to be 9.3 cats per sq. kilometre, with variation from 1.9 to 57 cats.
We then mixed these figures to calculate the nationwide estimate of 247,429 unowned city cats. Whereas the quantity shouldn’t be prone to be precisely proper, our statistical evaluation tells us there’s a 95% likelihood the true worth lies someplace between 157,153 and 365,793.
Obligatory cat microchipping is nice in idea — however the system is flawed
Why so many unowned cats?
The hyperlink between unowned cats and socio-economic deprivation isn’t completely stunning. Earlier work has recognised that fewer owned and unowned cats are neutered in disadvantaged areas. When cats are unneutered, populations can increase quickly.
There are a number of things which can clarify the affiliation between elevated human inhabitants densities and elevated densities of unowned cats. For instance, there could be extra pet cats in areas with extra individuals, which means extra cats that may produce unintended litters if unneutered, and extra cats that may be deserted or stray from dwelling. Additional, unowned cats will probably be restricted by useful resource availability. There could also be extra cats the place there are extra individuals as a result of cats have higher entry to meals in these areas, for instance from human meals waste.
What can we do?
We’d like continued analysis to enhance our understanding of unowned cat populations. The predictions from our mannequin improve in accuracy as we scale as much as broader geographic areas, which means our estimates will probably be extra correct at a nationwide degree in comparison with a avenue degree, the place there could also be different native variations in cat populations. Areas with the best human inhabitants densities particularly, equivalent to London, require extra analysis, as they weren’t amongst our unique examine websites.
Nonetheless, our analysis offers helpful perception into the size of the unowned cat inhabitants within the UK, and the way unowned cat populations could range throughout the city panorama. This data can allow cat welfare charities to direct their help to areas of best want.
The curious character of cats – and whether or not they’re actually extra aloof
Sadly, with out a human caretaker or a daily supply of meals, water and shelter, unowned cats in city areas are at heightened threat of many illnesses and environmental hazards. Though figures range, the life expectancy of an unowned cat has been estimated to be round 65% lower than that of a pet cat.
Frequent administration practices for unowned cats embrace rehoming of strays (cats which can be used to dwelling in a house however have turn into misplaced or deserted) for whom avenue life is unsuitable. Unsocialised cats – those who could have been born on the streets and never used to individuals (typically termed feral or group cats) – will be neutered and returned to areas, ideally the place there’s a cat caretaker who can regulate them and supply meals or a shelter. That is generally termed trap-neuter-return.
Our findings of an in depth affiliation between unowned cats and human communities counsel that profitable cat inhabitants administration in city areas may even require supporting cat homeowners to microchip their cats to forestall them getting misplaced.
Moreover, it’s necessary we help homeowners to have their cats neutered earlier than potential breeding age to forestall any unplanned litters. Our earlier analysis has highlighted how the long-term effectiveness of any trap-neuter-return and rehoming packages will be improved by concurrently working with communities to encourage neutering.
