1. Trauma When a cat is accidentally scratched by a sharp object while playing, or the paw is injured due to a fight, and the owner does not discover it in time, the pads of the cat's paw will become red, swollen and suppurative over time. In severe cases, secondary infection may lead to local ulceration. Therefore, owners must pay attention to the status of their cats at ordinary times. If they find any abnormality in their cats, they should take their cats to the pet hospital for examination in time. If it is determined that the cat was scratched by a sharp object, you must also look for foreign objects in the ulcerated area when debriding the cat. If there is any foreign matter, remove it in time. ​​​​​​​ 2. Contact with items that are too hot Cat's foot pads are actually relatively fragile. If they come into contact with certain items that are too hot, they can easily burn the pads. If not treated in time, the pads will ulcerate. Therefore, owners must usually put away these items that are too hot to prevent cats from coming into contact with them. If the cat is accidentally burned, anti-inflammatory treatment must be carried out in time. 3. Skin diseases Skin diseases are mainly considered to be secondary bacterial infections, which can cause infection and suppuration in areas such as between toes and foot pads. This is mainly related to cats living in humid areas for a long time. General symptoms include local redness, swelling, itching and pain. If this is the case, it is recommended to promptly consult a professional pet doctor for medication, or take the cat directly to a pet hospital for medical treatment.
