Here's why:
* Space: Cat carriers are too small for a rabbit to comfortably move around and stretch. This can lead to stress, discomfort, and even injury.
* Temperature: Cat carriers offer little insulation against cold temperatures, which can be dangerous for rabbits. They are prone to hypothermia in cold weather.
* Ventilation: Cat carriers can have poor ventilation, leading to a build-up of ammonia from urine, which is harmful to rabbits.
* Safety: Rabbits can chew through the materials of a cat carrier, potentially escaping or injuring themselves.
What to do instead:
* Safe and comfortable space: A large, draft-free area is ideal. This could be a designated room, a corner of a room with a divider, or even a dog crate (if it's large enough).
* Warmth: Provide a warm bed with blankets or a heated pad (never directly on the rabbit). Make sure the bed is safe and chew-proof.
* Food and water: Ensure a fresh supply of food and water is always available.
* Litter box: Provide a clean litter box with a safe and absorbent litter.
* Supervision: Monitor your rabbit for signs of illness or stress.
Important: It's always best to consult with a veterinarian for specific advice on keeping your rabbit safe and comfortable in winter.
