Cat-proof fencing using roller bars costs £8-£15 per metre and prevents most cats from climbing over garden boundaries. Oscillot-style spinning paddle systems cost £15-£20 per metre. A purpose-built catio ranges from £200 for a basic frame to £2,000 for a walk-in enclosure. Under the Animals Act 1971, cats have a legal right to roam in the UK and cannot be trapped or harmed.
