Our bother and sister duo, Samson and Delilah, sure sound like your little ones. These are ferals from a barn. Delilah was rescued first, and has been with humans the longest, and is still fresh and feral at times(at mealtimes you would not believe how sweet she is!). Samson, rescued in March, is really quite sweet. They will be ONE in July. We do use the squirt bottle at times, but perhaps you should look into Bach Flower Remedies to help with the bully behaviour....Good luck!!
