Heya,
I hope you find it more friendly here
we are still a bit keen on a bigger cage, but personally, as long as the ham is healthy and happy, getting all it needs, if the cage is a smidge too small its not the end of the world!
I havent grown fresh plants in the cage but mine love fresh basil, coriander & cress, I would try other herbs but those are what i know they have liked, but I think in the cage they would just harvest it, store it and it would go moldy, just keep an eye out for excessive storing of the fresh plants
I have seen some lovely natural set ups using lots of dori seed bushes, millet sprays, houses hand shaped from air drying clay to look like rocks, fish tank decorations like the bridges made of giant pebbles, lots of sand and using more natural looking bedding (bright pink carefresh wont be top lol!!) like megazorb, aubiose, and other such things.
I love wooden houses and toys, so they can make it look more natural using browns then bright colours
I wouldnt let the ham and cat play when you are not about, but if you are 100% they are safe, and you are there with them then its your call
We all would love to see the photos of your ham
