I have a 3 year old female Lion Lop rabbit, and she is not spayed.
She has been living with us for the past 1.5 years, and was in a very nice home before that. She is a lone bunny, and the lone animal in the house. She has had absolutely no issues in the past, and was a very nice rabbit who would let you pick her up, pet her, gives you licks, and constantly follows you around. Her cage is inside our house, and during the day when there are people around she is given the option to come outside and hop (maybe 9-12 hours a day).
For the past few days, I have noticed a very large change in her personality. Starting about 4 days ago, she had suddenly started humping my arm. That 'behaviour' lasted for only that day, and for the next few days she would not do that. But, the days after, she had gotten so much more grumpy.
She is still pooping, peeing, eating, and drinking fine, but acting very different. For an example, she would still come out of the cage to get food, but she would avoid me. She still eats out of my hand, but when I start advancing towards her she would run away frantically. Also, when I try to pick her up, she goes CRAZY... she runs everywhere she can. She doesnt seem to be in any pain.
Also, her timings have seemed to change; she is quite active only around 4-7am, whereas before she was active at 5-7pm.
Just this morning, she was on the upper level of our home with carpet, and she was pacing back and forth at her top speed; this got us spooked, because she only does this outside, and very rarely.
I would like to know what is the cause of this crazy behaviour, and how I could fix it. Thanks!!
