My Poor Rabbit.

Question
My rabbit is acting very weird. how can i find out whats wrong with her?

My rabbit is about half a year old. we have 2 rabbits at the same age. but my white bunny ,Bunners, is acting very weird. she is lying down lifeless and will only sit up if we lay her a certain way. when we pick her up its like she is dead in our arms. she has been stretched out since 7:30AM. what do i do?
11 hours ago - 4 days left to answer.

Its now been 24 hours since we found her like this, their has been no change. my black bunny, midnight, has been sitting with her for 12. we have been up with them all night. She has not been eating but she is drinking off our finger. her eyes are looking heavy now and her breathing is on and off fast. when she poops, its in big lumps of diarrhea, she dont even move when she does it, She also pees herself too. she will just lye there and do nothing. She will sit up if we place her a certain way though, she will be able to move her head and everything, but what scares me the most is when Midnight cuddles into her she shakes. What does that mean? we cannot afford to take her to a vet so how much longer do you think i will have left with my precious bunnies? I say Bunnies because Midnight is very attached over Bunners, and soon after Bunners dies, Midnight will die too out of depression, they were together their whole lives. Please try and give me some ideas that would help.

Answer
I have no idea what I could possibly do so far away. Have you tried to give her subq fluids under her skin? Have you tried to give her any electrolytes by mouth?
She is obviously dying and if this were my bunny I would be RUSHING her into a vet hospital. Part of owning any pet is being responsible for their medical care as well as their everyday care and feeding.

You need to get her into a vet NOW and hope that they can turn this around. You may have waited too long as it is.

I doubt if your other bunny will die of depression but she might from the same illness that is affecting this first rabbit.

Take them both in but especially the first one!! Sitting and watching your pet die when it could be treated is really not an option and not one I can advocate.

I hope you do get her some medical help very quickly.
