'Pat' named Oldest Living Mouse

Endangered mouse is a whopping nine years old.

An endangered mouse has received the title of Oldest Living Mouse in Human Care, verified by GUINNESS WORLD RECORDS.

Named Pat, the Pacific pocket mouse is currently nine years old, and has been raised by the San Diego Zoo Wildlife Alliance since birth.

Born on 14 July 2013, Pat was named after actor Sir Patrick Stewart, and was born in the organisation's first year of the Pacific pocket mouse conservation programme.

North America's smallest mouse species, Pacific pocket mice get their name from the pouches in their cheeks which are used to carry nesting materials and food. These creatures play a vital role in North America's ecosystem by dispersing seeds of native plants through their digging.

Dr Debra Shier, who established and oversees the Pacific pocket mouse conservation breeding programme, said: “This recognition is so special for our team, and is significant for the species.

“It’s indicative of the dedication and incredible care we as an organization provide for each species, from the largest to the very smallest. 

“This acknowledgement is also a symbol of appreciation for species that people don’t know much about because they’re not charismatic megafauna, but are just as critical for ecosystem function. These overlooked species can often be found in our own backyards—like the Pacific pocket mouse.”

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.
