I have 2 cats, a 7 yr old male-Rusty & a 1 yr old female-Jinxy. They get along most of the time these days except when it is time to eat. Jinxy becomes so aggressive towards Rusty as I am getting their food. She jumps on him & he hisses at her & they swat at each other too. I rescued Jinxy from the street in Dec & it took a long time before Rusty would accept her. Most of the time they get along now except when it is time to eat. As soon as they both get their food everything is OK. I'm not sure what is going on. Will time stop this?
