I know that you can’t use something that has a 3″ gap. I’m not really sure about 2.5″ but I wouldn’t risk it.

My buns can fit through 1″ -1.5″ square.

Nice looking gate, I can see why you like it. I’m guessing (yes only guessing) that the lionhead would be able to get thru, maybe even the angora. I would be a little afraid of them just being able to get their heads through the bars. If they moved too fast, they could possibly hurt themselves freeing themselves from it.

I haven’t done any gate searching myself, so don’t know all the available styles or costs, but… if -I- had decided that this was THE GATE I HAD TO HAVE… I would probably do some modification to it to ensure they couldn’t get their heads through. The spacing on the bars on my xpen are 1.5″ and my holland lop can’t put his head thru it. He CAN get half his face thru it, up to his eyeballs.

Your wood floors are lovely! I’m guessing this gate appeals to you because it has the design that is not only functional but also attractive to the eye. So I’m not sure if any ideas of modifying would take that appeal away or not. I would consider things like NIC grids zip-tied to it or maybe even something like weaving flexible clear-sheeting thru it, so you could still see thru it.

If their heads fit, the rest can follow. I remember specifically looking for NIC grids that were 2 inch squares or less. The ones at Bed Bath and Beyond were big so I didn’t buy them. I had to look all over town and take my tape measure with me. LOL

Yes, there is some concern about them hurting themselves. Only if they got caught while trying to get through and panicked though. Otherwise, simply squeezing through is likely to not cause any harm.

You know those baby gate panels that lock together and fold to make a circle? (http://www.ebay.com/itm/like/180825822401?lpid=82) … the parts that have the “gap” and not the plastic piece sticking in between the holes are a prime push through for my two if they aren’t connected very tightly, since even a little give lets my 8 and 6lb bunnies slip through. So, they can fit through really small holes you wouldn’t think they could even get half their bodies through, let alone the whole thing. lol

My buns are all adults less than 3lbs. The bigger one is more stocky bigger boned netherland/lionhead, who’s been up to 3.5lbs, mix; I don’t think he ever fit through though a hazard. The other two, netherland and lionhead, can fit easily.

It’s as LBJ says, if the skull can get through, the rest of the bunny can follow. And their skulls obviously look bigger than they are because of the fur. I’ve seen many wild rabbits fleeing from danger by getting through holes of 4×4 cm in fences. It says piong in the fence.

My Bam made it into a box under my bed where the gap between the bed and the upper edge of the box was little more than an inch. He sort of flattened himself. Then he had a good time in that box and created a lovely mess of the bed-linen I kept there.
