Unexpected pregnancies
The most obvious reason to de-sex your pet is to prevent unexpected – and more importantly, unwanted – pregnancies. All too often, under-resourced animal shelters fill up with unwanted litters from owners who neglected to get their pets neutered. If you don't can't look after or re-home a litter yourself, it's best to prevent it from happening in the first place.
It extends life expectancy
De-sexing gives your pet a longer life and can reduce the risk of some animals developing fatal health concerns, like certain kinds of cancer. De-sexing can help give your pet a chance at a healthy, long life.
No negative effects on their personality
It's a fallacy that de-sexing pets changes their personality. While there may be some sadness and resistance immediately after the procedure (likely aggravated by the cone around the neck), ultimately de-sexing will have positive – not negative – effects on your pet's character. You may find they're more playful, happier and have better focus.
It keeps them safe
Pets in heat love to roam the streets. This increases the risk of car accidents, getting lost or ending up in the wrong hands. De-sexing can help to reduce the risk of all these issues, making life less stressful for indoor pets and their owners.
