One of my cats has previously stretched up whilst on the window cill and caught her claw in the sealant. The sealant then breaks and dangles - brilliant game! Then of course she's found out that it works on the horizontal bottom ledge too!
So we're constantly getting the windows resealed and it's frankly boring!. Is there anything I can use instead of flexible sealant, or is there something I can put on top of the sealant to harden the outside?
Any solutions welcome APART from getting rid of the cat!
