What size harness should I buy for a 4 pound cat?

Most 4-pound cats will fit into a size small harness. However, it is essential to measure your cat's chest and neck circumference before purchasing a harness to ensure a comfortable fit. The harness should be snug but not too tight, and it should allow your cat to move freely. Here are some guidelines for measuring your cat for a harness:

- Chest circumference: Measure the widest part of your cat's chest, just behind the front legs.

- Neck circumference: Measure around your cat's neck at the base.

- Body length: Measure your cat's length from the base of the neck to the base of the tail.

Once you have taken these measurements, you can compare them to the size chart of the harness you are considering purchasing to find the best size for your cat.
