If your cat keeps eating the wire for the antenna on your motherboards built in Bluetooth you can get something like this without wires. You may have some of them on your router that you can try out to see if they work.
I bought a pair of these: https://www.amazon.com/Antenna-Wireless-Express-Extender-Security/dp/B06XB92KNF
I’m only using one but I haven’t had any problems with it in terms of signal loss. I bought these for a previous motherboard that used to drop Bluetooth signal all the time and they solved the problem.
They work just fine on the b550-I strix as well
