An 8 week old kitten is old enough to leave his Mum and join his future home. So for most of us this is the youngest age of kitten that we will ever find ourselves caring for. Be wary of breeders that offer to let you take a kitten home at 6 or 7 weeks old. Kittens under 8 weeks old are not ready to leave their Mums and litter brothers and sisters. If you have brought home a kitten younger than 8 weeks old for any reason, have a chat with your vet. They will be able to support you in giving your baby kitty the best possible care.

A kitten weight chart or growth chart is an important tool to help gauge proper kitten development. With or without their mother cat, a kitten should grow steadily, at certain rates, and a variety of changes should occur within a certain time frame. The biggest indicator that a kitten is developing properly starts with weight gain, according to a kitten weight chart.

Weight can be the number one indicator of problems in many cats, but where kittens are concerned, this is especially true. Kittens growvery rapidly, because in the wild, they would be expected to be weaned and fending for themselves by the time they are 12-16 weeks old. A kitten that is not growing is usually sick or may not be getting enough nutrition.

Behavior Of 8 Weeks Kittens

Eight weeks is a milestone age for kittens. They should weigh about two pounds, which means they’re ready to be spayed and neutered! They’re also fully weaned (you’re done with bottle feeding) and look more like adult cats. It’s a good time to start looking for their adoptive homes.

At this age, kittens explore confidently away from their mother and can jump. They are becoming more skilled and adventurous and will sleep and eat at regular intervals like adult cats. Kittens’ growth rate will start to slow at this point. They will continue to develop muscle tone and strength but won’t be doubling their weight in a matter of days or weeks anymore.

  • The kittens are extremely active, and the mother will have longer periods on her own.
  • The role of the human is to take an active part in the socialisation process without intruding, especially in the very early days. Take the time to not only play with your kitten but also to offer plenty of cuddles and familiarise it with being handled, in general. This includes frequently touching the paws, ears, and mouth, which will make basic health inspections, medicating, and claw trimming easier, as the kitten is brought up to accept this.
  • At this stage, kittens are eating four, small meals a day and, by eight weeks, should be eating mostly solids.
  • Once a kitten reaches 2 pounds, it is safe to spay, neuter and microchip.

Eight week old kittens need only tiny portions of food. Exactly how much depends on the type of food you have chosen for your cat. Wet food comes in cans or pouches and many 8 week old kittens will need only about four ounces a day.

Be guided by the manufacturers recommendations, and remember to give a little more if your kitten is a large breed. And remember that hunger is not a great indicator of need. Some kittens are very greedy. Your kitten will also need more if he becomes underweight or fails to grow at a healthy rate. This daily food ration needs to be divided into several small meals.

How Often To Feed Kittens 8 Weeks Old

Tiny cats have tiny stomachs. If you give your kitten too much to eat he will get fat, and if you give him all his daily food allowance in one or two meals, he’ll get diarrhea. This means that kittens have to be fed little and often. An eight week old kitten needs four meals a day. Breakfast, lunch, tea and supper.

How Fast Does A Kitten Grow?

Growing kittens under 6 months of age will weigh approximately their age in months. So, a 2-month-old kitten should weigh approximately 2 pounds, a 3-month-old kitten should average 3 pounds, and so on.

Don’t worry if your young kitten doesn’t follow this weight formula exactly, though. Each pet is unique. As long as your kitty has a clean bill of health from your veterinarian, your pet is on the right track. 

A kitten’s weight at 6 months of age and older is more variable between individual cats, since they are starting to get closer to their adult size and may grow at different rates.

Causes Of Weight Deficiency

There can be many causes behind your kittens barely gaining weight: the mother may be producing too little milk or the milk may not contain enough nutrients.

Whilst a cat produces milk for its offspring – this phase is called lactation – it needs 1.3 to 2.5 times more energy from its food. Its protein requirements in particular are increased. Mothers therefore need easily digestible food that is rich in nutrients and provides plenty of energy. Also always provide enough fresh water.
