My wonderful husband does not want to spay our indoor 5 month old kitten. He adores her & thinks spaying will change her personality. Someone said "Let her come into heat once & after he goes through that he will happily agree to spay her"...there is no way she can get outside and we have German Shepherds so no stray cats can come into our yard. We do not want her to have kittens. Question - will her personality change if she has one heat & is then spayed ?? - after one heat & spaying will she go back to being our sweet loveable baby?? If she sprays urine during her first heat will she then pee forever or will that habit go away??
