Golden Chinchilla cats typically reach their mature size around 8 to 10 months old, with their growth generally ceasing by the age of two. However, it's common for them to gain weight or develop fuller cheeks (known as "cheek puff") later in life, leading to a rounder appearance.
British Shorthair Chinchillas, in particular, tend to reach sexual maturity between 8 to 10 months, by which point their body size is largely set. Their physical development peaks around the age of two, although they may continue to develop fuller cheeks and a broader physique after that point. A six-month-old British Shorthair Silver Chinchilla can already appear like an adult cat. While their length won't change drastically, their weight is more fluid and depends on their nutritional intake. Adult cats typically weigh between 2.5 to 5.5 kg. Many owners will feed their kittens high-fat animal-based canned food. However, this practice is generally not advised, as the digestive systems of young kittens aren't yet fully developed, which can place a heavy burden on their gastrointestinal tract.
How to Feed Your Golden Chinchilla
First and foremost, remember that cats are obligate carnivores. Ideally, they should consume a diet that reflects this. A combination of beef, chicken, chicken/duck liver, and boneless fish is great, with some of the ingredients ideally cooked. However, some Golden Chinchillas are picky and prefer raw meat. If feeding raw meat, ensure they are properly dewormed. If you prefer a more convenient method, you can combine dry cat food with freeze-dried treats, such as capelin, chicken breast, small quail, egg yolk, etc. If you have the time, preparing a raw bone meat diet at home is the best way to ensure they are getting a balanced diet.
