Cat spraying!

[ohcluttergotme]

Hi, we have a mummy cat Pebbles. She is tiny & 5 years old. She had a litter of 5 web she was 8 months old. We stubidly kept 2 boys. They are all neutered. The 2 boys chase her, they think it's a game but she gets scared. She has started spraying in the house. We were not sure for a while if it was her, one of the boys or rogue cat coming in. We're now pretty certain it's her & it's cause she's scared.
Does anyone have any suggestions for what to do if your neutered female outdoor cat is spraying?
Thanks in advance

Yes it sounds stress related. The first thing I would try would be a feliway diffuser to calm everything down. You can buy them in Pets at Home, online or at the vets

Hi thanks Thecat Sorry only just noticed your reply!?
We came into the kitchen one night and a big, huge black cat was in our kitchen and had come through their magnetic cat flap, we now think this is who was spraying in the kitchen. This cat in the past has attacked all three of my cats quite viciously by biting them really badly and they all required vet treatment. I'm pretty sure he's not neutered as he is always fighting and he wanders around at night. I'm also thinking he may be the Daddy so feels some sort of claim to my garden, house, cats!
I've now started locking the cat flap at night and the spraying has stopped...thank God as was driving me insane.
Thank you for replying and will still look into the felliway diffuser as think my little girl cat does get herself a bit scared of the 2 boys.
