Hello! Your bunny sounds super cute and feisty. I have a feisty boy too. He is definately the boss of me! I just wanted to say that hay is meant to be at least 80% of a rabbit's diet. This is due to their unique digestive systems which require high fibre diets to prevent gut statsis, which is nasty and often fatal and causes a lot of pain - distended belly, bunny will stop eating and drinking and can die within 12 hours of onset. Not trying to be ghoulish but felt to let you know as I keep an eye on this too. My bunny really likes hay cubes, have you tried those? I'm from Australia so I'm not sure where you would get some. This is some info about this not being as nutritious as fresh hay due to the process of heating and compressing (it's just compressed hay in small crunchy blocks), but it's better than no hay. Also, I'm growing rye grass in small containers on my balcony, as hay is just dried grass, fresh grass is one solution. My bunny loves all fresh grass but decorative lawn grass is not rich in nutrients either, rye and there are some others if you google, are good options. Too much fruit can lead to diabetes as well. I use Oxbow pellets and they are high in fibre (22-25%). A lot of pellets contain wheat and grains, sugar, fats and other rubbish which rabbits don't eat naturally and have trouble digesting. I also put hay toppers on my bunnie's hay, dried herbs that are safe like dandelion flowers, rosehips, rose petals, there are lists of safe options online in many places. This makes hay a little more interesting and adds some enrichment in terms of foraging and vartiety like buns experience in the wild. Hay also keeps buns teeth trim, so I'm wondering how your buns teeth are? These grow very fast and need constant chewing to keep at a healthy length. Diarrhoea is a sure sign of not enough fibre in the diet and can be quite dangerous long term. Good luck with your little boss!
