Questions
Do indoor cats need a collar?
A breakaway collar with ID helps if an indoor cat gets out, but a microchip is the more reliable backup.
Cat Collar Accessories
Collar accessories should not interfere with the breakaway buckle and should stay small and light, as covered in the Cat Collars brief.
Cat Collar Bells
Bells go on a breakaway collar like the Rogz Catz line covered under Cat Collars. Keep them small, and skip them if the jingle stresses your cat.
Cat Collar Charms
Charms add snag points, so use only light, flat ones on a breakaway collar like those covered under Cat Collars.
