I have found that after a female has a heat cycle it does change their personality. She could be having a false pregnancy. Females go though hormonal changes after a heat cycle and their bodies act the same as if they were pregnant. Most of the time the personality change lasts about two months, the same length as a pregnancy, then they will become more playful and happy. Was this her first heat? Another concern would be if she has pyometra. Unless you plan on using her for breeding it would be best to have her spayed before her next heat cycle then you won't have to worry about the personality changes. Please keep us posted on how she is doing.
