Thanks for all your help.
I have another question, sorry for all the questions but I want to be absolutely certain I can care for a persian properly.
I have two tonkinese cats and I empty the contents of their litter tray into a bag every night and give them fresh litter.
When I get my new cat, the three of them will have two trays.
Should a persian be ok with the litter trays that are emptied once a day, rather than picked at several times a day? I don't want to distress him.
Again, many thanks.
