E-Collar Alternative Cats Dogs: After Surgey Wear. Recommended Vets COMFORT AND SAFETY - Used by veterinarians as an E-Collar alternative to protect abdominal wounds for cats, dogs, and rabbits. Increases mobility, reduces stress, accelerates healing, and reduces the risk of infection by keeping the wound safely protected. MALES VS. FEMALES - After Surgery Wear has a cut in the back to allow most female animals to urinate/excrete while wearing the product. To ensure the abdominal area is fully protected, the product does not have an opening for male animals to urinate. Before going on a walk or letting male animals outside, the product must be partially removed from the back legs and retied along the body (see picture in listing). SIZING  For sizing instructions, please refer to the size chart in the images and measure carefully. To ensure a secure and snug fit, the last pair of strings should be crisscrossed with the second last pair of strings (tie the left side of the last string with the right side of the second last string and vice-versa). PATENTED DESIGN - Adjustable strings ensure a custom and secure fit for animals of all shapes and sizes. Includes an adhesive hygienic pad (for sizes XXS, XS, S, M, ML, L) that should be placed onto the fabric to absorb any discharge from the wound. FABRIC - Specially woven fabrics deter most animals from excessive licking. Breathable and light fabric allows for constant air-flow circulation allowing the wound to heal safely. Fabrics are 100% pure cotton and hypoallergenic to prevent skin irritation. Machine washable (before washing, tie a knot at the end of each string to minimize fraying).
