My cat has decided to start jumping behind my tanks and chew my cords... I'm very close to getting rid of him... This will be my last attempt at solving this lol my tanks are around a foot or less away from the walls on stands I'm trying to think of something to run down the side to block the gap from tanks and walls. I have tried rolled carpet cardboard about everything I can find that will fit he still finds a way back there. I thought about chicken wire but I'm about positive he'd get thru that and it would look unsightly the only thing I can think of is some type of wood that covers the gap and goes up at least to the top of the tank and paint it black so it doesn't look so bad but I'm not sure how I would secure it I don't want to nail it into the stands and the walls are cement block. I'm sure some of you have ran into this issue and have better ideas than me thanks in advance
