Martha Stewart is said to be in grief after one of her cats was killed in a violent assault by her four dogs.

The 80-year-old entrepreneur described on Instagram how her 12-year-old cat Princess Peony was murdered by her dogs in an Instagram post.

"Burying the lovely and peculiar Princess Peony," she captioned the photo, which showed workmen digging a grave.

"The four dogs mistook her for an intruder and slaughtered her helpless tiny self."

Following the announcement, Martha Stewart posted a close-up photo of her Calico Persian cat with the comment, "This was the Princess Peony."

The late cat was born on May 11, 2009, and transferred to her farm four months later, according to her website.

Martha told TODAY last year about how her cats helped bring solace on her farm in Bedford, New York, through times of seclusion during the COVID-19 epidemic.

Princess Peony was one of three cats on her property, along with Empress Tang and a male cat called Blackie, according to the cookbook author and homeware expert.

The siblings were characterized as "beautiful" and "very unique" by Martha Stewart Living's creator.

She said that pets are excellent for kids and could even be treated as actual kids.

The icon even expressed her happiness that during the pandemic, people have come to spend more time with their pets.

Martha Stewart is also well-known for her love of animals, having hosted a Puppy Bowl two months ago and often posting about her French Bulldogs, Crème Brulee and Bete Noir.

She has a fondness for horses in addition to cats and dogs.

She previously claimed to have at least 20 cats, 25 dogs, two horses, three donkeys, hundreds of chickens, numerous sheep and goats, turkeys, geese, peacocks, quail, and homing pigeons, and even a slew of canaries and parakeets.

In 2020, she referred to her pets as a "wonderful bunch" and said that rearing animals is hard for the faint of heart as she strived to be an exceptional owner to each of them.

Martha apparently reacts to them in pleasant ways, while others are more distant and other animals entirely ignore her.

She does, however, recognize that they are aware of how much she cares about their needs and is aware of any challenges they may have.

"Each of my dogs requires a tremendous lot of care, and some need more training than others," she continued. "However, the benefits greatly surpass the effort."
