Hi there! I second everything said above. Now that it is summer, you should also be diligent to the threat of flystrike. I think that you will be able to find posts on this forum about it - I posted with pics about 11 months ago. I have just had mine treated with Rearguard which acts as a preventative and I keep the litter trays as clean as possible throughout the day by scooping out any 'wet' poops which might be there and which attract flies. I also put a few drops of lavender oil in the litter trays which really does help to keep the flies away. I line the trays with newspaper (drop lavender oil on the corners) and then put a small layer of hay or straw on top.
Can't wait to see pics from you of yours
