Current tenant in our Brisbane IP (house) has made a pet application for guinea pig (for their daughter). When given the choice, we generally choose a tenant without a pet. I had another IP where the tenant's cat became fascinated with round dots on the wall paper and started scratching the wall paper off and whole thing needed fixing. Just wondering what experience forum members have with guinea pigs as their own pet or in their tenants in IP. I understand the guinea pigs can cause some damage to the lawn (do they like digging)? We are generally happy with this tenant (family) who is otherwise looking after the property well. Do you think rejecting their pet request would put them offside or they are less likely to renew their lease at the end of the lease? We have been otherwise very good at meeting all their maintenance requests.
