Whats wrong with my rabbit!? please help im so worried :(?

take him to the vet as an emergency appointment! he might have something stuck in his digestive system, he is showing the same symptoms as my female rabbit when she had a blockage of hair stuck in her stomach... rabbit do not have the same ability's as cats do when it comes to coughing up something.. i took her right away, the vet said if we waited any longer she would have dyed. even with the medication it takes a bit for the rabbit to recover so it might be best to bring him in, have a cozy cage for him to rest, and stay stress free. he is probably in a lot of pain right now :(
