'''In urban areas the density of cat populations may be high, exceeding 50 cats per square kilometre.''' In a survey conducted by the author (Jon Bowen, 2013), 81% of 734 UK cat owners whose cats were allowed outdoor access indicated that their neighbours also had at least one cat that was allowed outside, and 66% reported seeing a neighbour’s cat in their garden at least once a week. Owner reports of the number of different cats regularly seen in the garden and the frequency of cats visiting the garden were both correlated significantly with the frequency of injuries due to conflict with non-resident cats. 41% of those households reported some level of home entry by neighbourhood cats, with 18.7% reporting that cats came in to fight with their cat and 25.6% reporting that cats came in to steal food. For households that had a plain cat door without security features (as opposed to a selective entry cat door that only allows resident cats in and out) the figures were significantly higher; 24.8% of cat owning households reported that neighbourhood cats came into their home to fight with their cats, and 39.4% reported that cats came in to steal food. Regular experience of this kind of home invasion, and subsequent injuries from fights with non-resident cats, are a '''significant source of stress for domestic pet cats'''. The fact that cats commonly take the risk of entering each other’s core territory in order to get access to food indicates that there are serious problems with the way that pet cats are being fed. | '''In urban areas the density of cat populations may be high, exceeding 50 cats per square kilometre.'''
