3 Main Things:

• • GPS Collar with replaceable / rechargeable batteries - you don't ever remove the collar - you pop an old battery out, put it on the charge, and pop a freshly charged battery back in.
    • Research brands - check UK

       

  • Microchipped cat w/ registry that provides search & rescue assistance (sending out flyers to local vets, shelters, rescues, local residents), and return-to-home transport and vet care
    • Home Again - any others?

       

  • Window Switch Guards - something covering the window switches on the door arms of the cab. 
    • 3D Safe Solutions (3dsafesolutions.com ) - custom snug-fit or low-residue double-side tape for many cab styles.  Designed and produced by a fellow OTR trucker
