We just use the Tesco's own baby sterilising fluid to clean ours. I figured if it's cleared for use with babies' bottles then it's probably all right for the kitty cats' toilet.

We empty out the litter, then add a capful of sterilising fluid to the tray, about an inch of boiling water, then wash it out with one of those disposable sponge things and then dry it with kitchen roll.

We don't really clean out the litter tray that often though as we use a really good clumping litter (Nature's Best) and have it quite deep, so just remove the clumps as and when. I have found that having it as deep as possible (a tip I got from PF! ) means we don't have to clean it out very often.

And you're probably right. However, the manufacturers don't claim it's effective in sterilising used bottles without them being thoroughly cleaned first and I think they have to stay in the solution for a given time for it to be effective. It isn't what you use - it's how you use it.

I might try something else next time, e.g. just normal bleach. How long would you recommend leaving the bleach in?

I believe 10 minutes is the golden standard and leaving things wet with the solution to dry on their own is the sensible option which will 'do'. I think dilute bleach (1:32) kills most things in 10 minutes, viruses, bacteria and fungal spores which is why it's also the disinfection regime where there is ringworm. If you don't like bleach then use what you like. I know some people don't like to use bleach around their cats but I've never had a problem, probably because the effective solution is so dilute.

I use boiling water, washing up liquid and bleach or disinfectant. Pretty much the same of most people above.

Havoc - Gosh, you are very knowledgeable on the cat litter tray subject. Where did you find out about the person called Diane Addie? So do you follow her advice?

Dr Diane Addie was a name in FIP research in the UK. I only say 'was' because she is now working elsewhere. I shouldn't think there's a breeder in the country who doesn't know her name. Her greatest gift to the cat world was in diagnosis protocols and many a vet would still do well to follow them. Far too many cats are still pts with 'assumed' FIP. Her research into transmission of Feline Coronavirus (which can lead to FIP in a small number of cats) is what led to the litter tray cleaning protocol.

The poster who brought up using baby's bottle sterilising fluid actually created an interesting parallel. The idea with both is to ensure all bugs are killed so it makes sense that the protocols would be entirely similar
