Liznya the Cat has amassed 9,500 followers on Instagram after her Russian over started posting pictures.
But commenters have started accusing the owner of “abuse” and asking how the owner could let Liznya “get so big”
In a lengthy post, the owner has explained why Liznya is so pudgy and defended their care for the cat.
“We have never tried to overfeed Liznya. Some people wrote we do it on purpose. How do you imagine that” they said.
The owners continued the post by saying Liznya is on a diet after being taken to a vet.
“It is true that our cat was pregnant and spayed after it, but we do not claim this is the exact reason for her to become obese,” they said.
“We wrote that she began to gain weight quickly since her pregnancy and even quicker after it.
“She has been to the vet many times and has changed her diet plan more than once during this time.
“Now she seems to have stopped gaining weight with her current plan, but still there are problems with losing it.”
Guinness World Records does not record the world’s fattest animals to deter owners from overfeeding their pets.
