Video: Cat Burns
Burns are very common in cats. They can be caused by thermal, chemical or electrical (electric shock) effects. The severity of a thermal (heat) burn in cats can easily be underestimated as it differs to some extent from a similar burn in humans.
The blisters typical of superficial burns in humans do not necessarily occur on the cat's skin. The hair in the burn area remains attached to the skin, but if you pull on the hairs and they come off easily, then the burn is deep and serious.
First aid for thermal burns: apply a cold water or ice compress for 20 minutes. An emollient germicide may be applied. Deep or extensive burns require immediate veterinary attention. Since it is difficult to immediately assess the degree of damage in a cat, in all cases of burns, the animal must be shown to a veterinarian within 24 hours.
Young cats that bite through electrical wiring while playing are often electrocuted. This can lead to severe skin lesions and pulmonary edema. Cats with this type of burn should be examined by a veterinarian as soon as you notice the fact of the lesion. Choking or coughing may indicate pulmonary edema that has already begun. In severe cases, the tongue and gums may turn blue. If the electrocuted cat is unconscious and cannot breathe, try artificial respiration. If, after an electric shock, the general symptoms of the disease do not appear, then after a few days you can expect the death of the burned area of tissue on the animal's face. Here, a veterinarian's supervision is necessary.
