Sadly today my little boy, Nippers has passed. We went on a trip to Michigan and a friend of the family was supposed to come over and feed and water my rabbits. She didnt tell us till the last day which we were up there in Michigan for 3-4 days that she did not come down and water and feed them. So thanks to her my Christmas present year was coming home to see my rabbit dead in his cage. So I was wondering if his brother who hes been with his whole life could possibly become sad or depressed from his brothers death, and do they realize that their friend has passed or is it just hey my buddy is gone where did he go, type of thing? I dont want to be freaked out if I see him in the corner of the cage not being his usual self and thinking that hes going to die too.
