I used to have a hooded tray, but I personally don't think they are that great an idea
I was lucky with Hamish and Misty cause they would both use the same tray with no Problem
then One day I heard a noise from the cupboard where I kept the bag of Litter, and there sitting in the bag
was Misty " taking a dump "
I did ask Him what the ell was He doing ?? but He did not answer, and just looked at me nonchalantly
I went and checked the Litter tray and there were 2 wee's and 2 poohs
I immediately cleaned out tray and everything was fine
after that ( I also got rid of the hood so I could see when it was needing cleaned out )
that same day I also discovered someone had weed on my work clothes ( probably Hamish )
anyway, I would get rid of the Hood, " so you can see when it's needing cleaned " and does the cat litter you use Clump ?? I used
the same Litter for Olivia that she was used to, but it did not Clump, I have since changed it to clumping stuff and the trays now a doddle to clean
hope this helps
