1. Oxygen depletion. When a room is closed off, there is less air circulating, which can decrease the amount of oxygen available to the cat. This can be dangerous for both the mother and her kittens, as they both need a lot of oxygen to stay healthy.
2. Lack of food and water. If a pregnant cat is locked in a room without access to food and water, she will quickly become malnourished and dehydrated. This can have a number of negative effects on her health and the health of her kittens.
3. Stress. Being locked in a room can be very stressful for a pregnant cat. This stress can lead to a number of health problems, including high blood pressure, weight loss, and difficulty giving birth.
4. Potential for injury. If a pregnant cat is locked in a room with other animals, she may be at risk of being injured by them. This is especially true if the other animals are larger than the cat.
If you need to keep a pregnant cat separate from other animals or people, it is best to do so in a large, well-ventilated room with access to food, water, and a litter box. You should also check on the cat regularly to ensure that she is healthy and comfortable.
