There are several types of litter available on the market that can be used for a British Shorthair cat. However, the best type of litter will depend on the individual preferences of the cat and the owner. Here are a few options to consider:

1. Clumping litter: This type of litter is made of clay and forms clumps when it gets wet. Clumping litter is popular because it makes it easy to clean the litter box, as you only need to remove the clumps and leave the rest. This type of litter is also good for controlling odors, as the clumps can be removed and disposed of before they start to smell.
2. Silica gel litter: Silica gel litter is made of small beads of silica gel, which absorb moisture and odors. This type of litter is long-lasting and does not need to be changed as frequently as some other types of litter. However, it can be more expensive than other types of litter, and some cats may not like the texture of the beads.
3. Natural litter: Natural litter is made of materials like corn, wheat, or paper. This type of litter is more environmentally friendly than clay-based litters, as it is biodegradable and does not contribute to the problem of waste in landfills. Some natural litters are also low-dust, which can be helpful for cats with respiratory problems.
4. Scoopable litter: Scoopable litter is similar to clumping litter, but it is formulated to be more absorbent and longer-lasting. This type of litter can also control odors effectively, and it is easy to clean. However, it can be more expensive than other types of litter and some cats may not like the texture.

When choosing a litter for a British Shorthair cat, it is important to consider the cat’s individual preferences and sensitivities. Some cats may have preferences for certain types of litter, such as those with a certain texture or scent. It may be helpful to try a few different types of litter to see which one the cat likes best. Additionally, some cats may have sensitivities to certain types of litter, such as those made of clay, so it is important to keep an eye out for any signs of discomfort or irritation.

In general, it is important to choose a litter that is low-dust and does not produce a lot of tracking, as British Shorthair cats have thick, dense fur that can easily pick up and spread litter particles around the house. Additionally, it is important to choose a litter that is effective at controlling odors, as this breed is known for having a sensitive sense of smell and may be put off by strong odors in the litter box.

In conclusion, the best type of litter for a British Shorthair cat will depend on the individual preferences of the cat and the owner. Clumping litter, silica gel litter, natural litter, and scoopable litter are all good options to consider. It is important to choose a litter that is low-dust, controls odors effectively, and does not produce a lot of tracking, and to keep an eye out for any signs of discomfort or irritation in the cat.
