Oh, yes, the poop trail is definitely territorial and should get better after Roger is spayed. (though it can take a month for the hormones to die down)
If you have a smaller cage, you may want to get a pen, like an x-pen to offer a little more exercise without allowing too much freedom. If you do this, be sure to protect the other animals that come near by because rabbits can bite between the pen bars. Especially if Roger is territorial. My poor Rucy got part of her lip bitten off by Bailey. Thank goodness a good vet repaired it, but still this is something you don’t want to happen – especially if it is near the eye.
I ended up wrapping a thin netted type of fencing around the bottom half of the x-pen. This allowed them to be near other animals, stay familiar with them, but not hurt them.
Regarding where to feed : Having food in different places doesn’t matter, but having it at those same places around the same time can help with tensions right now.
When things do settle down, and everyone is calm and happy, it can actually help with exercise and attention to have food spread around in different places. (Though keeping it around the same time is important)
Most people usually just feed food in one place, and really, it’s not a big deal, but by spreading out the location of food, it actually follows how a rabbit’s digestive system is trained to work. It also helps keep their mind and body active.
Example. I’ll stick their greens throughout the bars of their pen. And in some places they have to get on their hind legs and reach up to get. I’ll throw out their pellets, like birdseed on a sidewalk.
Out of curiosity, have you noticed if Roger gets more messy, more territorial when the time is nearing feeding time?
