FAQs
Breakaway collars only?
Yes for safety. Cats can catch collars on furniture / branches and strangle. Breakaway snaps under pressure. Non-negotiable for cats.
Harness for outdoor cats?
Yes for leashed outdoor walks. Vest-style cat harnesses (Kitty Holster, RC Pets) prevent escape better than collar. Train indoor first.
