I love cat stories with good endings like this one. I also have a rescue at home. She was found in a street being very skinny and telling everyone how hungry she was (she’s very vocal). The doctor who did the basic necessary treatment and who fixed her said her age was about 3 years, but she was rather small and very very naive at that time, so I’m pretty sure she was no more than a year old.
Her youth probably helped her to adapt to mostly indoor life. She still tends to eat too much too quickly, so I leave a spoon in her bowl to make it more difficult for her to suck in everything in 3 seconds and then throw it up.
At first her belly was 100% a trap, but now, 4 years later, she’s quite fond of belly rubbing.
