Ok so I know its not about raw stuff, but I thought I might put it out there.

I've got 2 lovely babies- 2 moggies who are now 1 3/4 years old (brother & sister) and I love them to bits, but there litter tray obsession worries me a bit.  They used to be outdoors cats, but I have moved interstate & the little delights *you can tell I'm obsessed with them* came with me, but they are now indoors cats. They are really anxious about their litter trays. After they do their business, they seriously scratch away at the litter for a couple of minutes to cover the smell. The little girl even scratches the walls. But they actually are very bad at covering their poo. So I am wondering if the little crystals hurt their feet? I am very quick to pick up their poos, so I'm sure its not because of a dirty litter tray.
I am concerned about the amount of litter that goes to landfill so I have been using the crystals & they have a tray each, although they seem to use each others. Can anyone recommend a better style? Also, if I get them a little cubby house litter tray- that is enclosed (not sure if you know what I mean), with the little flap, like their carry cages, would that help reduce their anxiety? Or are they just to stop the owners smelling the litter?
I would appreciate any suggestions & so would my feline babies.
Thanks!

They're called "Litter Kwitters" - I have one but have never got around to introducing the cats to it.  My two are both indoor cats with free access to an outdoor enclosure.  To teach them to use the Litter Kwitter I'd have to shut them inside and I don't have the heart to do it.  They love lying in the sunshine in their hammocks.   

I have a very spoilt Ragdoll cat and I use a 100% biodegradable litter made from wood pellets which i buy from oz-pet.  This stuff is so economical!!!  I clean out No.2's straight away and flush them down the toilet.  You need a proper sieve tray which you can also buy from oz-pet - the way it works is to sprinkle a few pellets in the bottam tray and then cover the top tray with pellets, when puss does a wee it turns the pellets to dust and i shake the tray a few times a day to shake the dust thru to the bottam tray - then no 2's are cleaned out daily and once a week i empty the bottam tray and sprinkle fresh pellets in.  The litter lasts for ages and ages and i have never noticed any smell whatsoever.
Google oz-pet and check it out.  I have to say the reason i use it is because before i got my puss i was researching different types of litter and what i read about using the crystals made me realise that it wasnt a safe product for cats - can cause terrible health problems.

That sounds really interesting Cas, I'm definately going to investigate.
Shells, with regard to your gorgeous kitties' somewhat obsessive scratching around after doing their business, I personally wouldn't be too concerned. My little girl is just the same - she honestly looks very embarrassed and acts as though she is desperate to get her mess all covered over. Since I bought her once of the covered litter trays it's been better, although she still glances around furtively before she goes in, like she doesn't want anyone to know what she's doing! Before I adopted her she was a stray and I guess it is quite an adjustment to have to go to the toilet in a little box when you're used to doing it wherever you want!
But, as I said, I wouldn't be concerned by it - I'm certainly not!

Hey Shells, that a bit off topic here so I'll start another thread to answer your question 

try changing the type of kitty litter...the recyled one is good...its like brown paper pellets nice and soft,and absorbent..

cats are so fussy and love to be clean

Usually in a pair of cats there is one who is the faster eater and I think the best solution is to seperate them or watch them while eating. I have to watch mine, one is quicker but she now comes out of their room cause she knows I come in and check, or she comes to the kitchen to share a mango with me, and my other kitteh can eat in peace.

I hope you aren't just feeding them raw meat and nothing else as this is not a balanced diet. Perhaps you should consider purchasing a veterinary-sold commercial diet or VeganPet Cat food (www.veganpet.com.au) which all have feeding guides based on age and weight.
