I have two almost 6 month old tabbies. I absolutely adore them.
Currently their litter trays are in the kitchen (only place for them) and sometimes I am not enjoying the dust and smells when we sit down to eat our meals in the kitchen. I am hoping a hooded litter tray will help?
I had one for a while, cat was very reluctant to use it with the door flap on (he knew how to get in and out, just didn't like being enclosed). He would use it with the hood on, but kept wiping poo on the inside of the hood and then getting it on his head! So we gave up. Didn't seem to help with the smells - changing litter brands worked better for that i reckon. I'd be tempted to try a top entry tray in the future though.
I got this one - super expensive but looks nice in the house, really does keep the smell in and also keeps tracking down a bit.
My cat took to using it easily enough but I don't think he likes it as much as his open tray (I still have that out and available as he went through a nasty time over the summer with a dodgy tummy) and best suited to young/small/agile cats as there isn't loads of room to maneuver around and get back out.
A couple of times he stepped in his poo trying to get back out...
