Hello,

I read somewhere that there is a special litter that detects blood in the
cat's urine (it changes colour). Does anyone know anything about it? I saw a
sort of orange (kind of salmon) spot in my cat's litter tray, and it happend
again (like 4 days later). Nobody else in my house sees the difference, but
I do (I am the one who cleans her tray, so....), and I am a little worried.

Thanks,

Catherine
