My cat was neutered 12 months ago but apparently they must have left some ovariab tissue in there because she is definitely on heat today! She has a vets appointment on monday for hormone tests and I think they will probably have to do a second surgery on her poor thing. Meanwhile next doors male cat is round constantly we are keeping her inside so he cant harrass her but she is unsettled etc. Does anyone have any good tips for calming her down etc
