Ever since me and my roommates moved into our new house, my 15 ft burm is acting weird/aggressive. I noticed the aggression by the weird body language she was putting out when i would move near her cage. Then today as i was cleaning the cage, she was acting weird again. Like she would move very fast from one end to the other. She wouldn't hiss at all. Just move really fast. Way faster than anytime before. So today i was cleaning the cage and shes moving all fast again. She moves so quick and so stealthily its kinda scary. So i was cleaning the cage on the one end of the 8ft/4ft cage and she attacked me. I mean she was all the way in one corner and my arm was all the way in the diaganol corner so she didnt even come close. She jumped about 3 ft in the direction of my arm with her mouth open. Scared the [bleep] outta me.
So now im spooked. I got a million questions but ill keep it simple...
#1 if she was to bite me, what is the most recommended method to get her off of me. I've read about a spray bottle with vinegar and a spray bottle with isopropyl alcohol and to just spray it in their face. Do these work? What would you recommend?
#2 is there some reason why she would be all of a sudden aggresive? i mean she would always come over to me when i would open up her cage but now she moves like she does when there is a rabbit in the cage?!?
If theres any questions, please ask id be more than happy to offer any info at all to help me out here heh. What do i do guys? Ive come here before for advise about all sorts of questions ranging from temperature to cage size and i have never been let down, so once again before any answers, thanks for the time
