Bun Not Eating GI Sounds/Tooth Grinding

Question
My 6 year old female (thought it was a boy until this year, tho some obvious other hints came before this year), who is normally happy, healthy energetic, nosy garden helper and very attached companion is not eating in the last 12 hours, lies flat on tummy and loud tooth grinding came today (wasn't present yesterday) and loud GI noises.  I observe McGreggor's droppings daily and for the last 2 days they are very tiny.  Just gave the simethecone this a.m. very scared because this has never happened before.  I took off work today to observe and watch inside.  I knew something was wrong last eve because McGreggor just laid around although is very lazy most of the time just wasn't his self and I could tell.  When I uncoverd the 3 story condo this a.m. he had not touched his pellets, hay, or green salad last night.  Any thoughts?

Answer
Dear Amber,

As the instructions in my profile direct, you must not ask for information on the internet when your rabbit is lethargic and not eating.  That should be considered an emergency and a cause for an immediate call to a good rabbit vet.

Please get McGreggor to a good rabbit vet immediately:

Read this, so you'll know what questions to ask, and what to do in the meantime:

I hope he will be fine soon, but he sounds seriously ill, and needs immediate veterinary attention.

I hope this helps.
