until recently the cat used her litter tray. however (non pet owners may be advised to stop reading at this point)I recently bought a covered litter tray in order to stop the dog from, ahem, snacking on any presents the cat had left him that we had failed to spot and flush away. she carried on pooing in the new tray but not weeing. instead she was weeing all over the house. yuck yuck yuck. we've put the old tray back. she is neither weeing or pooing in it. we are assuming the poo is happening in the garden (I'd rather it was in a tray but am just thankful she's not leaving them around the house) but she's still weeing inside.
I've trawled the internet and will try all the usual stuff - which seems to amount to using vinegar/baking soda to get rid of smells, making sure the litter isn't near her food, is in a safe corner etc etc.
we've also taken her to the vets to check for infection...but the problem is the vet gave us some weird litter stuff to catch the wee in to test it. the irony is that if we could control where she wees (and get her to wee in/on this weird litter stuff) then we wouldn;t have a reason to think she might have an infection.
