I find this to be a great product and I have started using it. I have one very important question: Is it safe to flush the clumps in the toilet? or Am I asking for problems in the future?  Thank you.

I personally wouldn’t flush the clumps.  Just my opinion, though.

On a related topic - I had a sifting litter box a few years ago and I had two cats who would ATTACK the sifter.  LOL I would literally find them jumping in and out of the litter box trying to grab the sifter and bite it.  I have no idea what they thought it was, but it was too funny.

I had to eventually get rid of the sifting litter box because of the mess they made playing with it.  :D

I routinely flush the clumping Feline Pine, although I have only two cats and scoop daily. I’ve not had any plumbing problems.  The basement toilet is an old 5-gal flusher, though, that may help.  One of my boxes is regular Feline pine and I scoop and flush wet “clumps” from it also.  When I had 4 cats it seemed like too much to flush, so at that time I did bag and toss.  If you live near the ocean, they don’t recommend that you flush b/c of contamination of the water with germs, makes sea otters sick?!.  I live in the Midwest and hope I am far enough from the sea otters that my flushing doesn’t do any damage.

When I bagged and tossed, I’d carry out to the trash bin, which gets pretty ripe with once a week pickup, so sure prefer the flushing.....I actually think my stinking garbage can may have been attracting stray cats to my property, not sure, but since I am flushing it all now, I see less of them.  I live-trapped two of them and sent them to the shelter (I live in a busy town, so they are at risk outside) where they could get cleaned up and have a chance to be adopted.  They were spraying my house with stinky tomcat urine and turned out to be intact males.  No one was taking care of them so I felt I did the right thing.

Hope some of this info is helpful to you!

You wouldn’t believe the size of some of the clumps I managed to flush down the stool.  When my two boys were still with me, they were on fluid therapy for CRF.  Needless to say, both of them urinated at least twice what a healthy cat would, so I always had huge clumps.  When the feline pine hits the water in the toilet, it breaks up.

I flush the clumps, but I break them up first.  No problems if you break the clumps up.
