Gypsy is now 4 months old. She has always nibbled us playfully when petting her. Over the last few days she has been making more little noises and nibbling more when people pet her. Today while I was laying on the sofa she jumped up to join me as she normally does. Only today she was a lot more agressive in her nibbling. She then started humping my arm. She left me alone then came back and continued to do the same thing. I asked my son to come down and get her as she kept laying on my feet or shoulder. As soon as he came down she bolted under the cage and is not interested in him petting her. I know she is too young to be neutered but is there anything anyone can suggest to help me. Due to the medications I'm on her agressive nibbles have left me covered in bruises. Normally she is happy for me, my sons and my BF when he visits to pet her. Also is there a reason she has chosen me over the men in the house to do this to. This is the first time she's done anything like this. And any suggestions are very welcome. I have teenage boys so understand her hormones are probably raging but 3 teenagers under one roof is hard to manage lol.
