TL;DR: Grober Pets Kitten Gro is a Canadian-made milk replacer formulated for kittens aged 0–6 weeks. It mimics queen's milk with balanced proteins and fats, making it suitable for orphaned, rejected, or supplementally nursing kittens.

Raising a young kitten without its mother requires a nutritionally complete substitute. Grober Pets Kitten Gro Milk Replacer is formulated to approximate the composition of queen's milk, giving neonatal kittens the nutrients they need during their earliest weeks.

The powder dissolves easily for quick mixing, which matters when you're feeding every few hours around the clock. It's a practical choice for foster carers, breeders, and anyone caring for a newly rescued kitten.

Specifications

Who is it for?

This milk replacer is intended for orphaned kittens, kittens rejected by the queen, or litters that need supplemental feeding because the mother's milk supply is insufficient. If you've taken in a young kitten through a cat kitten adoption near me search, a cat kitten rescue near me, or found a kitten for sale that was separated from its mother too early, a proper milk replacer is essential — cow's milk is not a safe substitute.

It's commonly used by foster carers, shelters, and breeders who need a reliable, easy-to-prepare formula 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.

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.
