for reference, i got my boy solomon about 3 weeks ago. he turned one on the 15th of may. he's fully white from head to toe, not a single spec of any other colour on his body. he's a house rabbit and lives in my room/upstairs of the house (he doesn't like the downstairs laminate flooring) and he has 2 litter trays. one in his enclosure and one for when he's out. i change them both at 10am every single day without fail. and the other hay that's in his enclosure gets changed once every 2-3 days. he has a puppy pad, then bunny litter, then hay in his trays, so 3 layers. it goes puppy pad on the bottom, litter pellets in the middle, hay on the top. he's perfectly happy, binkying, kissing, grooming, zooming etc but his feet have a yellowish tint, and i don't know how to get it off. his feet are dry and fluffy so no warning signs there, but they have a yellowy tint. i've tried wiping them with a damp washcloth with lukewarm water but it doesn't budge. no other health concerns apart from this one thing and i'm at a loss as his enclosure is as clean as it can be and when he's outside of it is as clean as it can be. he only goes to the toilet in his trays so there's no hidden wee he's standing in. is there anything special i can do? i'm at a loss
