Hi
Unfortunately because the device is soo new there aren’t really parts available yet so your best bet is probably to get a part from Sony
However…
If it’s something the a HDMI cable you can get them at most local shops
If unsure I recommend using the amazing guide to upload a picture of the cable that unfortunately got chewed(the end of the cable so we can tell what cable it is)

Hopefully this helps
Any questions please ask
Thanks:-)
