2 cat boxes with puppy pads &bed (Moon lake New Port Richey Fl.)

I have one corner cat box 21 3/4 L X 21 1/2 W X 10 1/4 D and a storage tote 24 1/2 LX 17 1/2 W X 13 D that was modified for my late senior kitty Harry. He had arthritis and kidney disease so we made the entrances very low between 1-2 1/2 inches high so he could get in and out of the box with more ease. The boxes are well used with stains and scratches but are both clean. I’m hoping another senior kitty could use them or they could be used with a kitten. One box we added a temporary wall piece so younger cats don’t push the litter out. I also have his bed which has also been washed my cat and the cats here won’t use it,not sure why. If you have a senior kitty these could help, they sure helped my little old man Harry.
P.s. I have unused puppy pads too. (Puppy pad senior cat tip cut them into squares for small targets with a bigger one underneath saves on pads and cost.)
