WILDLIFE- AND CAT-FRIENDLY GARDENS
To reduce the chances of cats catching garden birds , it is advisable to avoid feeding birds at ground level and to place feeders high off the ground ( RSPB , 2021a ). Bird feeders encourage birds to congregate more than usual , which increases the transmission of diseases and infections ( BTO , 2021 ). It is therefore recommended that feeding stations and bird baths are regularly cleaned with a suitable disinfectant ( BTO , 2021 ). Some diseases can cause death , which may lead to wider population decline ( BTO , 2021 ), and cats may be more likely to predate on weakened birds .
Where nest boxes are provided , they should be carefully located to ensure cats cannot reach them or sit by them . Placing spiny plants or an uncomfortable surface beneath bird feeding stations and nest boxes has been suggested ( RSPB , 2021a ).
Cats and wildlife benefit from fresh water and shelter in gardens . If ponds are present , these should have sloping sides to provide an escape route for both cats and wildlife ( Trevorrow , 2019 ). Log piles and tree stumps can provide a refuge for wildlife and a scratching surface for cats ( Trevorrow , 2019 ). Some garden hazards can be harmful to both cats and wildlife . These include garden chemicals such as wood preservatives for fences , and pesticides such as slug pellets ( Trevorrow , 2020 ). To create a hedgehog-friendly garden , any product that kills slugs , snails or insects should be avoided ( Hedgehog Street , 2017 ).
Conclusion
Not all cats are hunters , and some may be more proficient and prolific hunters than others . Although there is no scientific evidence of the impact of cat predation on bird population decline ( RSPB , 2021c ), and the frequency of individual killings is low , the cumulative effect may be more severe in areas with a high density of cats ( Cecchetti et al ., 2021 ). The welfare of birds and small mammals is likely to be greatly compromised as a result of hunting by cats . Veterinary professionals , especially RVNs , can support and provide guidance to cat owners – during consultations , through display boards and via social media posts – to encourage responsible cat ownership that includes considering wildlife . Awareness of cat-attack data , alongside owner-type identification , may encourage change . By suggesting positive ways to improve the welfare of cats and wildlife , more progress could be made in this subject area .
