What were you using before? I went through a brand test phase with Sammy because her preferences were so different from what Spockie used to like.
She let me know in no uncertain terms, by kicking it all over the cage, that she did not like what I’d used for years.
I think I tried 3 types, including a different kind of the same brand, before she left it in the litter box and calmed down. So that’s what I have to buy her.
I just wish I could hand her the car keys when I’m getting low…picky bunny.

When you clean up the floor after he pees on it – are you getting it really clean with vinegar? The reason I ask is because if the floor of his cage still smells ever so faintly of poops and pees, he might still think that the floor is an acceptable place to go to the bathroom.

My neat-freak husband litter trained all my bunnies just by being himself. He would clean out the cage pretty much twice a day if the bunny peed/pooped at all on the floor. He would go in first with the vaccuum cleaner first to get all the stuff off the floor, and then next with the vinegar to get all the pee off. It usually only took the buns a week to figure out what he was doing, and that the litterbox was the ONLY place to go.

What kind of flooring does Oreo have? If it is rugs or something absorbent, you probably are not able to get all that pee stain out so that may be prompting him to continue to use the floor.

At first for about 2 days after changing to the equine fresh he had no problems with it, its been within the last first days he will go in it sometimes, but the majority of it I’m putting in the box after he’s gone outside of it!

Meaning you are putting litter on the outside of the box too, then putting that soiled litter in the box after he goes outside of it? I would only put litter in the box and no litter outside of it or newsapaper or cloth. So the only absorbant material is in the litter box.

Hormones are very likely a factor in this loss of habits. How far away is his operation? I think he’s telling you It’s Time!

Melaleuca? Is that a tea tree oil based cleaner? Have you always used this? Could he be trying to cover the smell?

It very well could be hormones but I think it might be that since you switched litter it no longer smells like oreo’s cage and they feel like remarking the territory with poop and pee.  Maybe once Oreo gets used to that bedding and it becomes part of their normal environment he will stop.  Well, hopefully!  My rabbits after I clean their cages seem to mark for a few days and then stop and use thier litter box.  Good luck!

I definitely think it’s the hormone thing. When I first got Happy he was about 10-12 weeks old and for the first month or so he had perfect litter box habits – I just put the box down, threw in some hay and he jumped in there every time. Then puberty hit and everything changed! He peed and pooped just about everywhere but his litter boxes! I would throw his poop and pee soaked paper towels in the boxes and throw my arms in the air crying “Why? Happy Why?” Then about 2 months later I had him neutered and within 3 days he was my perfect little trained bunny again and boy was I relieved! Now he rarely leaves a stray poo and hasn’t peed anywhere but in one of his boxes in months (he’s a free range bunny so he has several in his room). So just be patient and hopefully after his neuter he will go back to his good boy habits.

My husband told me I need to quit being such a neat freak about his cage, but I can’t help it, every time I see his sheet wrinkled, or a pellet out of place I have to fix it. LOL

haha! Well that may be another cause, they don’t like us messing with their space much. I try remember that but am forever in there with dustpan and broom.
Bring on the neuter I say!
