Curled Ears and Polydactyl Paws#
Highlanders develop signature backward-curled ear cartilage in their first few weeks of life. They frequently feature extra polydactyl toes, requiring routine claw trimming.
Healthy Body Condition Scoring for Growing Kittens#
Because individual genetics, frame size, and bloodlines cause natural variations in weight, hands-on body condition checks are the best way to evaluate healthy growth:
- The Rib Feel: You should easily feel your kittenβs ribs beneath a light layer of tissue without applying firm pressure.
- Waist Contour: Looking down from above, there should be a gentle, visible taper behind the ribcage before the hips begin.
- Abdominal Tuck: When viewed from the side, the lower stomach should slope cleanly upward toward the hindquarters.
Feeding & Nutrition Guidelines#
- High-Quality Protein First: Choose kitten recipes that list named real meats (such as chicken, turkey, or salmon) as the first ingredient to build sturdy muscle tone.
- Support Proper Hydration: Offer wet canned food daily alongside clean, fresh water fountains to promote lifelong urinary tract and kidney health.
- Portion Calibration: Avoid leaving massive bowls of dry food out at all times once your kitten approaches adolescence to prevent excess fat accumulation.
