Hi everyone. Clayton and Grumpy have now been installed into their new aviary, and seem to be settling well. I've attached pics. However, we have a small black problem called 'Shy' - a little local cat who has taken to sitting on top of the enclosure (despite it being over 8 feet tall), causing some irritated squawking to emanate from the parrots as you might expect. I like this cat and want to deter him humanely rather than endlessly chasing him off. Has anyone here had any luck with commercial cat repellents or any other methods I could try? Thanks for any advice!
