I have two hooded trays. I always take the lids off as my cats hate them. Mine are nice high roofed so they feel like they have lots of space (which they do).
Good luck.

 

You might have better luck just getting high sided clear tote boxes and cutting a hole for her to get in and out. I think it would be very difficult for a 16 year old cat to adjust to an enclosed hooded litter box. (and I hate them, they hold in odors )

I did this for my elderly girl a while back, because she had arthritis and megacolon and had trouble squatting up right long enough, So I gave her a box with tall sides and a hole cut, so she could lean against the sides to support herself. (I also put puppy pads under the litter so her feet didn't slip)

Currently I have two stand up pee-er and the high sided totes work great. I don't cut a hole for them, they jump over the side, but for a senior cat it may be better for her to be able to step in.

I do not put the lids on.

 

These are fantastic - as the lid folds back 1/2 way in itself there's room for even the tallest cat to stick its head out when going for a poop

They do come in a smaller size too but that's the one I have & might be best to go big for an older cat not used to a covered tray

I would never leave a flatp on a hooded tray as some CTS are scared of it closing behind them and being shut in the tray - and nasty smells can build up too

 

Another thing to consider is a hooded tray like that really isn't going to work for a stand up pee-er. The pee will run down the sides and get into the join of the hood and tray. That will be a nasty mess to clean every week.

 

I've recently got one of these, but from Jollyes on offer for £14

I too leave it open at all times and all three cats are using it as it has their preferred litter in it. I've still got the storage box with another litter in it but only a couple of wees in it for the last 10 days so they must be happy with the lidded tray

The back of mine is about 9" high so a normal size cat going up the side should not reach the seam. I agree if the pee completely stood up it might be a problem

 

The bottom section of the bigger Cat it one is over 11 inches at the back and still over 9inches at the front so should be deep enough I'd think

 

I'd be concerned about the size of the slat openings on top, I had a covered litter tray from P@H and Willowbee managed to get her leg caught in the opening when she jumped up on top of it, she screamed the house down and was absolutley terrified, I managed to get her out unharmed but I'm always wary now, from the picture you really can't tell how wide they are.

 

Looking at that litter box makes me shudder! LOL. I can't imagine any cat wanting to be so closed in while trying to toilet.

Think how airless it is in there, and how smelly. And dusty. I think cats should be able to poop and pee with as much headroom as they need, as THEY think they need, not feeling the need to crouch too low. Very bad for a cat's back. My youngest cat, almost 5 years old, is only 7 pounds but she has a very high crouch when she poops. She would find a cover intolerable.

Not good for lungs either, all the dust in there.

And cats don't like to be cornered. They want to be able to see what's coming when they are toileting.

Just because a cat is using it, doesn't mean it doesn't cause him discomfort, remember, cats hide discomfort.

I think cats should have free space and air around them, and a good view of what may be approaching, when they toilet.

 

B&m are currently selling hooded trays for £9.99, I have one for mine he doesn't mind the flap but you can easily take it off, the tray is very deep so I doubt a cat could wee or poo over the side.

 

I'm not a fan of hooded trays although that was what I originally bought - there really isn't much room in there and I don't think they make a lot of difference in terms of litter tracking everywhere. Hugo in particular used to spend hours in the hooded trays digging and scratching - don't think there was any pleasure involved, he was really quite neurotic about it - but he's much more nonchalant since I removed the covers. One of our litter trays has a clip-on rim which possibly avoids the chance of a cat accidentally peeing outside the tray - Hugo has had a couple of accidents, but never with this particular tray. Basically the cat can't squat right next to the edge of the tray - I did wonder if they wouldn't like the rim, but the tray appears to be just as popular as the others (more so if anything), so I assume they must like it.

 

Thanks for all the suggestions I will look into the tote box.
The tray I have for her is one from pets at home it was £8 large with the rim that goes around but she just peed all over it so I threw the rim out.
She doesn't stand up she squats but she squats too close to the end so therefore some pee or all of it goes over the floor.

 

Is it always the back of the tray?

If so, something like this might work

It seems to be at the back more yes.

Might be worth a shot before trying a covered one if she's never had one before

I know someone who has several cats and swears by this tray!

I'm thinking it will be my next one for Archie mine have a Catit Jumbo each just now but I've been trying his with the hood off so it can fit in my ensuite (he's always had a covered one)

He's coped without the hood fine (it's still enclosed by walls on 2 sides & the loo on the 3rd so I guess it still feels secure to him) - and it slopes at the sides & back very similar to the Cleany one (he does tend to create mountains of litter at the back of the tray / sometimes pees on the side at the back too)

The front dips very slightly as well which should be good for an older cat too
