It's quite normal for a cat to purr excessively when introduced to a new environment. This is often a reaction to unfamiliar surroundings, indicating that the cat feels uneasy or even frightened. When your Ragdoll cat arrives at its new home, avoid overwhelming it. Provide food and water, and allow the cat time to adjust at its own pace. It's also crucial to schedule vaccinations within a week of the cat settling in to prevent the onset of diseases.

Reasons for Excessive Purring in Ragdoll Cats in New Environments
Cats may purr excessively when facing new surroundings because they feel strange, uncomfortable, and afraid. This is a common response, and it's beneficial for the owner to be present but avoid disrupting the cat. As the cat gradually adjusts, the continuous purring will decrease.
The acclimatization period for a new cat can be approximately one week. You can speed up this process by placing familiar items, like their previous toys and food bowls, near the cat. The familiar scents can help the cat adapt to its new home in as little as three days.
Precautions When a Ragdoll Cat Enters a New Home
It's common for a Ragdoll cat to show a lack of appetite or refusal to drink initially in a new house. The best course of action is to not disturb the cat but instead provide a tranquil space. Leave food and water nearby and allow the cat to adjust without pressure.
A cat's resistance may weaken when they move into a new environment, so maintaining a comfortable temperature is important for their well-being. Additionally, it’s vital to keep the indoor space clean, especially corners, to prevent skin infections like ringworm.
Continue to feed the same brand of food and follow the feeding schedule provided by the breeder or shelter during the initial days. You can transition to a new diet later, once the cat has fully settled in. Furthermore, it is essential to ensure the cat gets vaccinated within the first week of adapting to its new environment to protect against contagious diseases.
