Swheat Scoop does a marvelous job here for me with six cats in the house. The smell is a lot nicer than wet clay.
Did you do a gradual change over or all at once?
I wish you luck with Gizzy.
We have a top loading washer so it is very hard to wash out comforter and throw blankets (the huge ones you get at fairs and ribfests), I have lots of vinegar but no rubbing alcohol. Do I wash them with vinegar and detergent or just vinegar or get some rubbing alcohol and run them with vinegar? How much for each? Would a steam cleaner work on the mattress?
When I wash the blankets from the catuary I use approx 2 cups of vinegar and a bottle of rubbing alcohol (it's cheap) and the regular soap. If I still smell the urine (I do have a few sprayers out there) then I wash it again just using the vinegar and rubbing alcohol. Normally twice gets rid of the smell.
A steam cleaner works on furniture. Can't see why it wouldn't on a mattress. If I'm wrong I am sure I will be corrected.
If the blankets are that big then take them to a laundromat to wash them. They normally have oversized machines for use. I have a top loader too.
