The paper published in the Veterinary Record by Dr Jane Murray in the Department of Clinical Veterinary Science at Bristol University and colleagues, aimed to estimate the number of UK domestic cats and dogs and identify the characteristics of their owners. The figures are also useful to the animal health and welfare professions, including rescue charities, which can use these and future estimates to assess population changes.
In 2007, a telephone survey of households randomly selected from the electoral roll revealed that cats and dogs were owned by 26 per cent and 31 per cent of households, respectively. The number of owned cats and dogs were predicted by two variables: the number of people in the household and the geographical location (London/rest of UK) of the household. UK census information and mid-year population estimates of the number of households and the average household size in 2006 in England, Wales, Scotland and Northern Ireland were used to estimate that UK households owned approximately 10.3 million cats and 10.5 million dogs in 2006.
Characteristics associated with cat and dog ownership were also identified. Cats were more likely to be owned by; households with gardens, semi-urban/rural households, households with someone qualified to degree level, respondents who were female and respondents who were aged less than 65 years. Cats were less likely to be owned by households with one or more dogs.
The likelihood of dog ownership increased as the household size increased. Dogs were more likely to be owned by households with gardens, rural households and less likely to be owned by households with someone educated to degree level and households with cats or children aged less than 11 years.
Female respondents and those aged less than 55 years were more likely to report dog ownership than other respondents. Dogs were less likely to be owned by households with one or more cats.
Dr Jane Murray, Cats Protection Lecturer in Feline Epidemiology, commenting on the research, said: “The study has shown many common factors relating to cat and dog ownership, such as a garden and rural location, but it has also identified some notable differences.
“In particular, the difference in the level of education achieved by a household owning cats and dogs. The reason for this association is unclear. It is unlikely to be related to household income as this variable was not shown to be significant but it could be related to household members with longer working hours having less time available to care for a dog.
“Past reports have suggested that the number of pet cats exceeds the number of pet dogs in the UK. However, results from our study suggest that there are similar numbers of domestic cats and dogs.”
The researchers recommend the study is repeated in 2011, (the year of the next scheduled UK census), as any increase or decrease in population numbers will enable pet ownership trends to be monitored.
