To ensure a healthy kitty, I recommend feeding wet food 2x per day with limited dry food. The higher quality food, the fewer vet visits you will have in the future!
I switch up between smalls, viva raw and weruva.

Smalls- Fresh Human Grade Cat Food
Viva Raw- (I gently cook but not needed)
Weruva Wet Food
Farmina N & D or Instinct Kitten Dry Food

Cats need access 24/7 to fresh filtered water! Make sure to replace with clean water daily.

Supplements:

Adored Beast Products are my absolute FAVORITE!

Felix's Flora- Species specific probiotic (gut health)
Photo Synergy- Super Antioxidant (fight inflammation and disease)
Rebalancer- if Vaccines have to be given, this is a supplement I definitely recommend

Bene Bac Probiotic gel (1X week for maintenance)
