GI Stasis questions, I'm worried sick :(

Hi everyone,
Virginia is about 5 years old mini lop. In the last 3 months she has lost her bonded mate, bonded with a new bun, been treated for ear infection and had a month on panacur for e. cuniculi. Then 2 weeks ago she had her teeth filed, her vaccinations and a flea treatment. Her appetite has been slowly decreasing for a couple of weeks and so she went into GI Stasis 3 days ago. My vet is quite rabbit savvy and saw her immediately. She’s now on pain meds, fibreplex, and antibiotics. (I’m a bit wary they will upset her gut but trusting the vet on that.)
I've been feeding her critical care with a syringe for 2 days, and syringing in water too. Yesterday she seemed to perk up a little bit, ate some plantain and dandelion leaves and nibbled a couple of pellets. But this morning she's gone downhill. Lying flat, depressed, turning her head away from the critical care. She's not pooped or peed at all as far as I can tell for 2 days. Now her new bonded mate has stopped eating too and is lying next to her, very depressed. So first question is how long will it take before she regains the will to eat, and what about pooping/peeing? How can I tell if it's a blockage? Is there anything else I can try to help her and also how do I stop her mate from also going into stasis?
Sorry that's a lot of questions but it's Sunday and I can't even speak to a vet till Monday morning!
Thank you so much for any help

hi have you spoke to your vet are they both ok

Hi Sucha, is everthing ok? I have read about homeopathic treatments for GI stasis, maybe you could try that? Take care!

Thank you for your support. Both my bunnies passed away before seeing the vet this morning

So sorry to hear that! Wish you all the best with this terrible loss

I'm so sorry for your loss

I'm sorry. My gf and I lost one not to long ago from gistatis. Have 2 in not the best shape now also.

Thank you for your kind words everyone. I’m so heartbroken

I'm so sorry for your loss you must be devestated

I am, thank you for your thoughts

Sucha, we lost our sweet Peachy very suddenly last week in a similar way but I can't imagine if we'd lost both bunnies at once. So sorry for you loss.

I'm so sorry for your loss. I can't imagine losing 2 at once, it is hard enough losing 1. All my sympathy to you. I am so so sorry.

Ohhhhh our hearts break for you!!

I’m sure many of us know the heartbreak of losing a sweet bunny, even if after only a short time of having them. They have a way of tugging at our souls.

We lost our sweet Bailey day after New Year’s to GI stasis. It was devastating. I can’t imagine losing two at once. Sending hugs and sunshine your way. Your bunnies are now binky free at Rainbow Bridge.

I’m so sorry to read of the loss of your buns too Peachybun and Bailey. Kale I hope yours are recovering. I’m still in disbelief and as this came only 3 months after losing the first one I have many questions in my head about the underlying cause. Sadly I’ll never know. The only comfort is I tried my best. Thank you everyone for the kind support it really means a lot to me.
