Biscuit, the 37-pound tabby who is looking for a home, has gained national attention since his plight became public; more than 110 people have offered to adopt him.
Workers had feared Biscuit might never get adopted because of his size, but callers wanting to give the cat a home or pay for his care flooded the animal control facility all day Friday.
Teresa Gilley, lead animal control officer, said she is keeping a list of potential owners and plans to review them next week before deciding on a home for Biscuit.
“The reaction has spiraled out of control; it's been unreal,” she said.
The cat's story, which was published on Friday morning’s front page of the St. Louis Post-Dispatch, was picked up by news websites across the country as well as London and Australia.
Callers included a representative of CNN personality Anderson Cooper, who inquired about the possibility of booking Biscuit on a show next week, workers said.
An official with Banfield Pet Hospital, a national veterinary hospital chain known for being in PetSmart stores, has pledged to give free wellness care to Biscuit for a year.
Biscuit is more than twice the size of a normal male cat, and since he got to the shelter a week ago, he's been put on a diet.
He is neutered and about 4 years old. He has had two previous owners, the most recent being a woman who gave him up after she moved into an apartment that did not allow pets.
Biscuit is the heaviest cat the St. Charles shelter has ever had, but his temperament is easygoing, and he enjoys being petted.
“Hopefully, we'll find him a nice home or a rescue group that will help him get the weight off,” Gilley said.
Anyone interested in adopting Biscuit or any of the other animals can call Gilley at 636-949-3395.
Meanwhile, Gilley said Biscuit doesn't seem to have let his 15 minutes of fame go to his head.
“He's still kind of laid back,” she said.
