Spaying: This procedure is done on female cats, and if done at a young age, can even help prevent mammary cancer. Even if done later in life, it prevents baby kittens from appearing, and also does away with the annoying heat cycles. The cat’s ovaries and the uterus are removed. The procedure usually requires an overnight stay in the hospital, and has a quick recovery time.
Neutering: Done on male cats, this entails removing the testicles through a small incision in the scrotum. It doesn’t change your cat’s personality or aggression level, but will likely curb your cat’s desire to roam the neighborhood and will change the odor of his urine when marking his territory. The procedure could also curb the marking behavior itself.
After-Surgery Care
Whether your cat was spayed, neutered, or operated on for tumor removal, you’ll want to give them time and a comfortable space to recover. Keep him in a
crate or cage for the first day or so, and feed him small amounts of food and water until it’s clear he’ll keep it down.
Stitches should be removed about 10 days after surgery, and should be removed by a professional. It also gives the vet a chance for a post-op checkup to see how the cat’s general condition is. If you notice any redness or swelling around the stitches, contact your vet immediately.
Keep your cat from biting or licking his wounds to prevent infection or further irritation. If you can’t keep him from them, you might have to put a cone collar on him for his own safety.
