Hi Basil,
Your story sounds sadly familiar. Have you asked your vet about the possibility of E cuniculi? It often causes increased urination. It’s incurable, but symptoms are alleviated and it goes dormant with 28 days of this stuff. The test is expensive, but the medicine is not. Maybe you could convince them to give it a go. If it’s not it, it’s harmless medicine.
As for the clean up, I understand. It had gotten to the point where every 6 hours wasn’t frequent enough for Cincinnati. At one point, I actually was using clumping litter, with the vet’s blessing. I work, so the 6 hours routine was impossible most days. Something had to give. It was also insane: doing a box four times a day including the middle of the night should be no one’s status quo.
Thankfully, there’s carefresh! I love this stuff. I’ve tried so many litters. Nothing touches this for absorbency. It’s available at Petsmart and lasts a surprisingly long time. It’s vacuum sealed, so you need to fluff it in the box. Then a bag lasts for several weeks.
I’m sorry that you’re getting tired of rabbits. I’ve been there. The care of Cincinnati is not what I signed up for. Daisy is ~10% of the work he requires, if that. That said, he is a life, and I love him. Love isn’t something you say, it’s something you do. It’s the only feeling that is also a verb. Basil won’t find a better home. Surplus rabbits, even healthy ones, are a dime a dozen. If there are any minors around, consider what rehoming him would teach them too.
I don’t see the point in the dog comparison, they’re totally different species with different ways of communicating. Every species I’ve ever interacted with has “returned” just as much as any other, just in different ways. You have to be quiet to ‘get’ something out of the less demonstrative. Besides, 99% of dog owners don’t realize their dog’s potential, by not doing one of three, necessary things: socializing; training; grooming. I love dogs that can check those three boxes.
How about trying carefresh and a high sided cat litter box?
