So in case this helps anyone today I have seen some success! Previously I’ve searched for answers on the forum and so feel I should journal anything of use.
I took the biscuits down to a very small amount. Played with them in the morning, cleaned and swapped out any hay and water. Then I intentionally went upstairs and didn’t come down again for a number of hours. Then I fed them some parsley and mixed some grass into their hay. I wouldn’t normally feed the parsley middle of the day but I was worried they might end up with some hair blockage and have heard it might help digest some of it.
Success! Poop had become a better size, still black on the outside but hay based in the middle! I also swapped the kale for romaine lettuce and the spring greens for celery and urine is looking less milky!
I’m doing full tray clear outs twice a day so I can properly monitor but i think fresh hay mixed with grass might be working as well as dropping the amount of calcium in their greens! I’m also of the opinion thT because they’re so cuddly they might be eating less hay because they prefer to play when someone is around so we will be proceeding with the extended periods of no disturbance as they just aren’t used to it.
Tomorrow I will try mixing the bulk of their biscuits into the hay and cutting some more grass. In no rush to go back to kale even though they love it. Although selective science has given me the scare of a life time they do seem a bit bouncier and more mental and less hungry so maybe it’s a good thing.
For the one that is a chronic dieter I’m adding some sunflower seeds to his diet regularly to keep him on the straight and narrow as I’m not sure anyone has the heart to go through that again.
