Preening is an important part of a parrot’s daily routine. Preening toys are exceptionally important to birds that are housed alone as they can help deter feather damaging behaviours. HARI Smart.Play Preening Block will provide companion parrots with hours of enrichment and entertainment as they untie, preen, and chew the multi-coloured sisal ropes and knots. Sisal allows your parrot to reproduce feather preening behavior. It can help prevent feather picking. The base is made from solid pinewood painted with non-toxic bird-safe vegetable dye and is easily installed/hung with the included lead & zinc free, nickel plated quick link and chain.
