Grober Pets - Kitten Gro Milk Replacer
Description
TL;DR: Grober Pets Kitten Gro is a Canadian-made powdered milk replacer formulated for kittens aged 0–6 weeks. It's designed to approximate queen's milk, making it a practical option for orphaned, rejected, or supplementally nursing kittens.
Raising a neonatal cat kitten without its mother means providing a nutritionally complete substitute around the clock. Grober Pets Kitten Gro Milk Replacer is formulated to mirror the composition of queen's milk during a kitten's earliest weeks.
The powder dissolves quickly for consistent mixing, which matters when feeds happen every few hours. It's a reliable choice for foster carers, shelters, breeders, and anyone who has taken in a young cat kitten.

Who is it for?
This milk replacer is intended for orphaned kittens, kittens rejected by the queen, or litters needing supplemental feeding when the mother's supply is insufficient. If you've recently brought home a young cat kitten or rescued a litter separated from its mother too early, a proper kitten formula is essential — cow's milk is not a safe substitute.
It's commonly used by foster carers, shelters, and breeders who need an easy-to-prepare cat kitten food during the neonatal period.
Feeding & use
Follow the mixing and feeding instructions on the product packaging, which specify the powder-to-water ratio and feeding volumes by kitten age and weight. Feed at body temperature using a kitten nursing bottle, and discard any unused reconstituted formula after each feeding.
Newborn kittens are highly vocal — the cat kitten sounds you hear during feeding times are normal cues for warmth and food. Kittens typically transition to solid food between 4 and 6 weeks of age; speak with your veterinarian about the right weaning schedule for your kitten.
