Hi again and thanks for you advice! Yes, I would not leave wet hay just laying around due to spoilage. Always a good point to make.
As my gut feeling told me, this issue would progress, and I would need the vet sooner.
The respiratory issue has stabilized or mostly subsided but he is not eating again. He will pick at his food, GO CRAZY for a certain kind of treat, and eat bits of cardboard (which I am not happy about…) He has pellets (that get replaced often..), fresh hay (that gets replaced often..) and water, but he just wants to eat cardboard. He is not the biggest fan of veggies, but he gets kale and parsley to pick at (right now, what is available).
So I have started him on some CC to supplement the little that he does eat. Temperature is good. He is just not a happy camper.
Wondering if the respiratory issue is related to a tooth problem (after he had his teeth done in the spring, all of his problems cascaded..) since he does not want hard food. Although the one treat is pretty hard… and the nasal discharge is on one side. (It is clear, not thick or yellow.)
And then I wonder if all of this is related to the significant molt (biggest of his life – but he has no mites or skin conditions – all fur has grown back) that he is finishing up. I have brushed him daily but worried he could have still ingested enough to get a hairball. He is secured in a pen when I go to work but who knows how much hair he ingested since he loves to groom.
Going to get his appointment moved up.
People are telling me that he is an older bunny so “let him go” as in euthanasia, but when he is feeling well, he is back to binkying, digging, hopping around, and is still quite territorial! He still has quality of life, but I just need to get to the bottom of what is going on with him.
I get it that stress from his procedure + age has weakened his immune system and we are perhaps dealing with chronic pasturella, e.cuniculi, etc, but I at least would like to know.
