Ancol Acticat Gloss Reflective Cat Collar Ancol Acticat Gloss Reflective Cat Collar – Safety Buckle cat collars have a special break-away buckle, specially designed to snap apart if the cat is in any difficulty. All Ancol cat collars have bells attached. The RSPB website also states ‘that cats equipped with a bell returned 41 percent fewer birds and also 34 per cent fewer mammals than those with a plain collar.’ Warnin If using liquid flea treatments we recommend removing the collar until there is no trace of the chemical on the cat’s neck area. The chemicals from the flea treatment may react with material and also the plastic on the collar. This prevents the safety clasp from opening as it is designed to do.
