It saddens me to have to respond to this same question yet again.
The reason it saddens me is that, for some reason, the folks at PermaScoop have decided that the best way to sell their product is through mis-information and fear-based marketing, rather than simply putting out a quality product and having it sell on it's own merits.
To specifically answer your question on the "toxicity" of the Forever trays, please know that I went through a fair amount of research before choosing rigid PVC. As I've said in other posts on this topic and will say again -- I wouldn't want to jeopardize your (or my) cats in any way.
The Forever Trays are made from rigid PVC. Rigid (also known as uPVC or unplasticized PVC) as used extensively in piping and other applications, such as:
- drinking water piping and drinking water units
- food service
- swimming pools/piping
Rigid PVC is FDA (Food and Drug Administration) approved for the above, and is also certified to meet American National Standards Institute/National Sanitation Foundation Standard 61 for safe use in drinking water service. Yes, your drinking water, not just sewage and drain piping. It is also commonly used in the irrigation piping that waters the fruits and vegetables we all eat.
The information the PS folks are selectively using is outdated info that is (was) focused specifically on the debate surrounding phthalates, a compound that is used to soften rigid PVC for other applications -- such as the bags used to carry blood plasma, toys, etc. Even in that regard, there is no conclusive current evidence to prove any of the claims, and there is an equal amount of data to support this (see the statement by one of the co-founders of Greenpeace elsewhere here at LBC). Just to put things in a more realistic perspective -- if you have vinyl seats or even cloth seats with vinyl trim in your car, you are sitting on plasticized PVC that used phthalates, and probably have been doing so for years with no ill effects. Vinyl seats in cars have been (and continue to be) made from this same form of PVC -- we're just used to the more common name of "vinyl".
If you look through all the posts I've ever put here, I've never, ever said anything derogatory about the Permascoop folks. In my view, they were just someone else providing an alternative for people using the Scoop Free. It's too bad it had to come to this.
There are currently well over 500 very positive feedbacks posted on Ebay, plus several others you can also find posted both here at LBC and on Amazon regarding the Forever Tray.
Regarding the other parts of your question -- both units should take about the same amount (approx. 4lbs) of crystal litter. There are numerous posts elsewhere here at LBC with more details on litter, changing frequencies, etc.
I hope this answered your question.
