single pringles!
I would say it definitely depends on the rabbit and their situation! Most rabbits do better with a companion. That said, I have a single bun now and she seems quite happy imo, binkies, explores, flops, eats well. She was very aggressive towards other rabbits at the shelter so she was adopted out to us as an “unbondable” rabbit. Although I don’t really agree with the idea that any rabbit is unbondable, and may get her a friend in the future, she is single with us for now
Our general routine, Thor is free range: On weekdays, I would say that we spend about 2hrs in the morning and then 6 hrs in the evening home with Thor, and maybe out of that we spend 3-5 hours interacting with her directly. She gets lots of grooming time and likes to sit on the couch with us in the evenings to “watch” TV. We also spend some time playing with her/laying on the floor. I’d love to do an agility course as well, that sounds like fun! So in general I would say I spend about the same amount of time with her as you do, and she seems quite happy (we have had her for about 6 months).
Every rabbit is different, but I wouldn’t feel obligated to get her a friend as long as she seems happy and not bored.
