hi, i just spayed my cat last week. Since I brought her back she has been eating once or twice a day.She is not willing to play anymore and the only thing she does is sleep.She looks a little bit depresed. The first two days i thought this was normal because of the surgery.There is no sign of infection in the scar.It has been a week now, is this behavior normal,if it is, how long does last?ThanX
