. Both sexes in ferrets are funky, & neutering does reduce it - U really cannot keep an intact M ferret as an indoor pet, the oily fug gets into every soft surface over time, as the odor is airborne & highly resistant to removal. Even neutered ferrets have stinky pee & poop - keeping the litter box clean by removing stools promptly every day [as U would for a cat], plus using a safe clumping litter to “grab” urine, & WASHING both the litter box & the ferrets themselves, is required. Ferrets toilet in CORNERS, so their litter boxes are triangular - they also need a high “inside corner”, as they like to hike their bums up, so the walls of the litter box must rise to the corner, & slope down the wall. Deeper is always better, as that allows for more litter depth & less risk of poop or pee going over the edge. I bathed my neutered ferrets at least every 2 weeks with a mild shampoo [SLS free, no “dandruff” removal or flea-killing stuff, plain organic shampoo]. It doesn’t take long, they are only 15 to 20” long tubes of short smooth hair. ;—D If they got funky in between by rolling or laying in the litter box, I just moved the bath schedule up. I also washed their cloth furnishings - hammock, tunnel, etc - weekly, all together in a large lingerie bag, or individually, each in pillowcases. Like cats, NEVER use “Pine-Sol” or other strongly-scented toxic cleaners around ferrets; Method all-surface cleaners are safe & nontoxic, organic options, & 7th Generation is another safe, environmentally clean brand. Even the litter box or the cage should never be cleaned with Pine-Sol, Lysol, chlorine bleach, or other toxic choices. // Hot water & ordinary dish detergent is also safe, if cost is a problem. - terry .
