How To Keep Cat Off Stereo Equipment?

Have 2 since they were +/- 2 months and were able to learn audio anything is Yes, in your turf but N/A for their amusement/vantage point(s)/napping/anything. 

Clio' is Ev's lap, Ginger reminds me of Tuxy, who was a reserved kinda guy.

I want to build them a catio....but not so long ago lost Betty to a bumper.

Zed suddenly Bridged with a GI issue suddenly and expensively.

Reluctant to test Fate.

Clio' has bonded to dog Sunny; 15 years of off/on again cats, she could give a squat.  She and The G stay out of each others' food, cool with each other.

Squirt gun if any critter forgets, hasn't occurred for quite awhile.

*Raps skull*  Knock on wood. ;)

Cat’s are territorial and since you probably don’t lay down on the stereo stuff you have they think oooh mine! There are a few ways to help you but do not  squirt Ms whiskers with a little water pistol or dump essential oils on your stereo! Lol

try to put the cat in another room and give them a space to make their own base camp with their bed there and a litter box near bass camp not tucked far away in a corner!

I have never been able to understand why people keep cats.  They are free-loading bastards that don't empathise with their keepers one little bit.

Anyhow, to solve the problem, choose between putting the kit in a cage and putting the cat in a cage.

I had a girlfriend that moved in with her cat a few decades ago.  I would routinely carry the cat out of the listening room because of the fears cited by the OP re-fur getting in components.  Eventually the cat learned the listening room was off limits. I knew the relationship with my girlfriend was over when the door to the listening room would suddenly open up and the cat would be tossed into the room
