a friend brought a cat round to me a couple of days a go she had to cut an elastic band off her neck. she had a deep cut round her neck but it dosent seem infected. The people who own the cat have brought her round to see if i want her. Iv had the cat but dont know if i should cover the wound or not to stop her scratching it and it becoming infected. i have another cat im worried they might fight she hasnt been taken to a vet and i cant afford to take her till next week. Any advice.
