hi, i have 2 ferplast cages and the base has a slight raised pattern which is a nightmare to clean ,it shreads kitchen roll when trying to wipe it dry after cleaning. i could sit there for hours sanding it flat but then it may make the base pourus and hold smells,,,,,,or I'm thinking of buying plastic sheets ,cutting & sticking to the base, if i do i need to run a sealent around the edge so wee etc doesnt get under the edges ,is there a selant that is pet friendly for odours or if they nibble it ,thanks
