It's worth having extras of these as soaking them prevents any food drying hard on them. My girl is fed 4 small meals a day as she is adopted following her original owner's death. For the last year she was with him she developed severe flea, tick & worm infestations & her body was almost bald. After 3 months we are seeing huge improvement, but little & often is beneficial. The whole feeding system has helped her so I recommend people buy it & get plenty of extra bowls too.
