I am curious about which if I long time use igloo house, will the urine smell cause respiratory issue?
how often is recommended?No, just clean the igloo house regularly. Lots of members use these houses with no problems
how often is recommended?
I cleaned the cage once a week, but I have not cleaned the Igloo house. Is it fine?However often is felt necessary and will probably vary depending on number of pigs being kept together and how much they love the igloo. A pair that use other hideys and rarely use the igloo will need it cleaning less than a group of 10 whose preference is that very igloo. If it smells of urine then it isn't being cleaned often enough.
So could I use water to wipe with paper towel?I wipe mine daily with a warm wet cloth to remove any muck, and give it a good wash in soapy water once a week, don't forget to rinse it off.
