Personally I find that a flea comb is better at detangling rather than brushing off loose excess fur, especially if your rabbit’s fur is very fine.

That said, I do use a flea comb in combination with a lint roller on my bun. Is the head of your comb round or sharp? If it’s not sharp, that should be alright as long as you are careful. You can also try a lint roller (a lot of people here do), but make sure to roll it a few times on your clothes first so that it’s not so sticky that it hurts your bun when it tugs at the fur too hard.

Is it sharp ended? Would it cause irritation or discomfort if you ran it over your own skin for an extended period of time? These are both big no’s.
Rabbits have very delicate skin, much more sensitive than ours so if something feels irritating or hard to us, it’s much worse for them

My rabbitt’s have thick coats, so we use a wide tooth comb, to get rid of tangles, then a slicker brush, which gets the majority of excess hair, and then finally a plastic fine tooth comb. The fine tooth come is only to brush the lengths of fur on the face-so moustache and beard and ear fluff
We do have a metal furminator-but the tooth length isn’t deep enough to actually reach the skin, and it’s angled to avoid it in the first place.
Slicker brushes for small animals are probably the best- the metal is fine and will bend under pressure to stop too much tugging at knots or tangles, and the tips are plastic coated to protect the skin

Those combs, to me, don’t look like they’ll be very great for removing fur (depending on coat type) more apt for detangling fur

To be honest hay is a far better mode of keeping her digestive system in good health. Blockages are usually a result of stasis, not a cause of.

As for the use of pineapple and papya there is a fair bit of debate over weather they are actually helpful- Papain (found in papaya) and bromelain (found in pineapple) may help to break down mucus binding an obstruction, allowing it to slowly break up and pass. However, there is no evidence to suggest that these enzymes break down keratin, which is what hair is composed of. They are both very sugary and can actually cause some harm to an upset digestive tract
Generally 1/2 teaspoon per pound of rabbit is the most that should be given in a day.
I know my girl regularly refuses pineapple because she doesn’t seem to like the acidity of it.

I give my lion lop a pineapple & papaya digestive supplement by Oxbow, he goes absolutely mad for it & I haven’t noticed any ‘bracelet poops’ since he started having it (maybe 3 months ago?). Might well be a placebo haha but can’t ignore the results!

I used to use a flea comb type thing which didn’t work that well, then a friend suggested I try the furminator. I actually got a knock off from Amazon (!) but it works GREAT. He’s generally not a fan of being brushed so I do it while he’s munching hay so he all but ignores me xD

You could try gently trimming the fur around her eyes if it’s particularly long. Also be sure to brush from front to back, away from her eyes. If she gets loose fur in her eye, she should be able to blink it out. You may also be able to get some eye drops from the vet if it’s severe – I had some recently for my bunny who was getting loose dust in his eyes while we were packing up the house to move.

I have found that a rubber brush works well for getting the fur off of my Julep. I also have the comb that I bought from the shop here on BinkyBunny. I only use that when she is blowing her coat and things are crazy. Have you tried using a lint roller? If you get an off brand that isn’t super sticky it can help a lot. I agree with Heaven about trimming the fur around her eyes and about using eye drops. You can also find saline eye drops that will work and should be much cheaper. I have bought and used those if Julep seems to have some redness in her eyes while she is shedding heavily.

That looks like an eye booger. I’ve seen it in my bunny’s eye before. It started in the middle of his eye and eventually moved to the corner of it. He managed to get rid of it himself when he was cleaning his face, so I don’t think it’s an issue unless it’s still there after a long time. Some people just help the bunny remove it by wetting a cotton swab (Q-tip if you’re in the US) and gently cleaning it off.
