Due to the rarity and high price, some families may be deterred from raising other cat breeds.

2. Requires high maintenance costs: The curly hair of the Selkirk Rex cat is one of the most distinctive features of this cat, and this curly hair requires special care and maintenance. Curly coats can become tangled and knotted, and their skin can become inflamed and infected if not brushed and trimmed regularly. To maintain the health and beauty of your Selkirk Rex, regular clipping, grooming, and bathing are essential, which can result in high maintenance costs.

3. Difficult to feed: Selkirk Rex is a relatively fragile cat that is prone to health problems. This type of cat may have respiratory problems, digestive problems, allergic reactions, and more. This makes raising this cat require a higher level of responsibility and attention, especially when it comes to food selection and daily care. To ensure their health and happiness, regular health checkups and professional veterinary services are essential.

4. Insufficient information: Due to the low popularity of Selkirk Rex cats, some families may not understand the characteristics and requirements of this cat. This may result in a lack of knowledge and experience about how to care for such cats, resulting in a relatively low level of interest in and understanding of them.

In conclusion, the Selkirk Rex is a very beautiful and unique cat, but raising this cat requires a higher level of responsibility and attention. If you are interested in owning this type of cat, you should seek the advice of a professional cat owner to learn about the special care and maintenance they require.

Also, be sure to obtain a Selkirk Rex from a reputable breeder to avoid supporting irresponsible breeding practices.

In addition, for some people, they may prefer those common cat breeds because it is easier for them to find information and resources, and it is easier to get support and help from other cat owners.
