Fur could fly at will readings across the country as almost a third of pet owners have included their dogs or cats, according to research.
And the study also found a quarter of those quizzed have officially named a guardian to care for their furry friends when they are gone.
This trend was sparked by stars such as comedian Joan Rivers, who provided for her four rescue dogs, and fashion designer Karl Lagerfeld, whose Burmese cat Choupette inherited a sizeable chunk of his £231million estate.
While most people do not have this kind of fortune to leave to their pets, the average amount set aside for them was between £1,000 and £5,000 to cover food, vet bills or their favourite treats.
And for a nation of animal lovers, it was no surprise that 54% of those polled would prefer to leave a legacy to their pet than a relative.
A third said they would overlook a sibling, while 17% would shun partners and 15% would overlook their children in favour of their furry friends.
The research, commissioned by online pet care marketplace Rover.com to mark Free Wills Month, also found 38% had not considered their pets future if they were no longer around.
Adem Fehmi, Rover’s canine behaviourist, said: “No one wants to think about their beloved dog outliving them.
“However, no matter your age, it’s important to make sure your wishes for your furry family members are known by those around you, and to put plans in place to ensure their care.”
But he stressed it was important the guardian “not only loves your dog but truly understands their unique needs, routine, and personality”.
They should also spend time together as this “will ease the transition, ensuring your pet remains happy, secure, and well cared for”.
