It's nice to know that you're using a product which isn't harmful to your pets but I found that hot water did a better job. I have a cube which i literally just hose down so I've no need for this product.
Works fine, spray is good as it delivers a fine even spray so you're not wasting any product. Nice smell - but a bit strong perhaps for a chicken?
Small print also reveals that this product is harmful to aquatic life (not just your pet goldfish but the water system in general). Most products of this nature though are probably the same. Will attempt to find an alternative though when this has finished.
