If you use clumping litter: how long would 15 litres last you?

[MrsBertMacklin]

I think I've been using far too much; used 15L in 3 weeks for one indoor cat.

The tray is the large Pets at Home one and it takes about 3 litres just to cover the base. What depth do I need from there? Enough to cover my fingernail if I stick my finger down to the bottom of the tray?

You need it deeper than that, then just remove clumps - don't change it all like you do with other litters....

I have 2 indoor dats and 2 big tests - a 40 litre bag of oko plus lasts ages.... I do a complete change about once a month (when it's getting dusty) and top up as needed in between...

You need it deep for it to clump properly - about 2 -3 inches deep ....

2 big trays not tests... Bloody iPhone

This makes sense, thanks. I've been doing full tray changes once a week, because huge slabs of litter are clumping at the bottom of the tray and causing smells even after being scooped.
Sounds like I've been suffering from false economy!

I've been cleaning out the lumps daily and then once a week declumping, then washing the tray. though I put the old litter clumpless back in after cleaning and top it up a bit. I have it at about 5 cm deep

Not too sure if this is OK as I've very new to this life with a cat

You may find you need a deeper tray or a covered one too... Sometimes they can spread litter around quits vigorously if it's deep....

But if it's deep enough you won't get slabs of wet litter.... It'll firm balls DNS be easy to scoop out...

Just one further tip. If you have it deep enough, the pee will go into a round/oval ball which doesn't usually reach the bottom so is easily lifted out and wrapped for disposal. If, though, for some reason - lots of scratching plus a bad aim for example - it's best to have a firm scooper and not those plastic things with holes in them that usually accompany the trays. I use either a metal flour scoop or a cheap metal garden trowel. (Poundland-type shops sell the latter but you may have something languishing in a shed anyway.)

Both of those have firm metal sides which act almost as sideways blades to get up any pee which sticks on the bottom. And being metal, they're easily washable.

There should have been an 'it goes wrong' in there somewhere.

What Cozie said! We have it quite deep, maybe 3/4 inches, but the wee forms into charming balls that are easy to scoop. It does mean you spend a bit of time truffle hunting for poos sometimes though....

2 cats, 2 trays, OkoPlus. I scoop 2/3 times a day, top up once a day and do a full change once a month or so as they seem to enjoy a fully clean tray and immediately deposit enormo-turds in it. The 40L okoplus bag lasts maybe 2 months here, or possibly even longer.

We spend SO MUCH less buying the big OkoPlus bags than when we were getting the smaller bags of CatSan from the supermarket, and the wee balls being flushable is marvellous.

10 litres of the OkoPlus seems to last me around 6 weeks/2 months for 1 indoor cat.

Thanks all. Will be doing a major top-up once I actually have enough cat litter (see other thread started tonight).

Side thought: Spent the weekend posting online about stuff that absorbs cat wee. What did you get up to?
