I have a 5 yr old female(spayed) & a 3 yr old male(neutered), they have been together for 3 yrs now and have loved & played great with one another, until a few months ago when the female started attacking the male for no reason..we got woke up @ 1:30 in the morning to the female peering at the male under the covers & just all of a sudden went after him, she always ends up hurt but keeps going back. We have tried separation, ignoring bad rewarding good and now even prozac but now she's losing weight & sleeping all the time & still wants to fight him..
Any and all suggestions are very much welcome..
