Cat coat colour linked to aggression, study suggests
Cats with tortoiseshell and calico coats tend to be more aggressive towards their owners.
Torties and calicos found to be the most challenging
 
Cats with tortoiseshell and calico coats tend to be more aggressive towards their owners than cats with other coat colours, a recent study suggests.

The findings, published in the Journal of Applied Animal Welfare Research, back up the long-held belief that such cats are often the most challenging.

Led by Dr. Elizabeth Stelow from the UC Davis Veterinary Medical Teaching Hospital, the study was based on an online survey of over 1,200 cat owners.

The survey did not reveal the focus of the study and simply asked cat owners question's about their feline's behaviours. Participants were asked to select a colour category and written description that best fit their pet.

The researchers found that torties and calicos are more likely to scratch, bite and hiss during interactions with people.

Perhaps more surprisingly, the survey also revealed that cats with white and black, and white and gray coats are slightly more likely to engage in those behaviours.

The study is thought to be the first of its kind to look at the relationship between coat colour and behaviour. Commenting on the findings, Dr. Elizabeth Stelow believes that there is scope for further investigation.

Speaking to US news website Sacramento Bee, she said:  "We thought the findings were very interesting and we would love other researchers to take the baton and run with it, to look at the genetics of why this may be happening."  

Tortishells and calicos are reputed for being more temperamental than cats of other colours. Torties are a mix of brown, black, amber and red while calicos are mostly white with patches of black and orange.

Because two X chromosomes are necessary to produce their colouring, the majority of both types of cats are female.

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

UK's BSE risk status downgraded

The WOAH has downgraded the UK's international risk status for BSE to 'negligible'.

Defra says that the UK's improved risk status recognises the reputation for having the highest standards for biosecurity. It adds that it demonstrates decades of rigorous animal control.

Outbreaks of Bovine Spongiform Encephalopathy, also known as mad cow disease, have previously resulted in bans on Britain's beef exports.

The UK's new status could lead to expanded trade and better confidence in British beef.

Christine Middlemiss, the UK's chief veterinary officer, said: "WOAH's recognition of the UK as negligible risk for BSE is a significant milestone and is a testament to the UK's strong biosecurity measures and the hard work and vigilance of farmers and livestock keepers across the country who have all played their part in managing the spread of this disease.
