Substrate and cleaning query
Hi Everyone,
I'm sorry if this sounds like a very silly question but how often should substrate such as topsoil be changed?
When my hermans was younger he just had newspaper which I would change every 2-3 days but obviously that's not really a reasonable timeframe for changing topsoil. But what is? 3 weeks? a month? Do you scoop off any visible poos to stop it becoming smelly?
Also, what is the advantage of mixing sand with the topsoil?
Thanks for all your help in advance,
Carol (and Reggie)
