Proportion of pet cats registered with a veterinary practice and factors influencing registration in the UK.

Registration of a cat with a veterinary practice is likely to be a critical factor for access to key preventative medicine. A cross-sectional study was conducted to collect data in the United Kingdom on the registration status of cats and potential explanatory variables. These data were also used to identify potential sources of bias associated with selecting controls from veterinary registered populations of cats due to differences between registered and unregistered cats. Cat owners reported that 13.6% (84/616) of their cats had not been registered with a veterinary practice since living at their current address. Multivariable logistic regression indicated that unregistered cats were significantly more likely than registered cats to be entire, to have not been vaccinated within the previous year, to be living in households in Northern Ireland and in households with an annual income <£10,000.(1) Whilst the neuter status and the vaccination status of the cat are likely to result from non-registration, the household location and annual income are factors that can be used to inform future interventions designed to increase the proportion of veterinary registered cats.
