THE RSPCA is warning Victorians to keep an eye on food, decorations and presents around their pets to ensure everyone has a safe and happy Christmas.

The animal welfare organisation said as thousands of pets and their families across the state enjoy the festive season together, it was vital to remember some foods and Christmas items were hazardous for animals.

Chief vet Bronwyn Oke said pet safety was often overlooked at this time of year.

"Some pet owners don’t realise certain foods are actually dangerous to animals and are much more serious than just an upset tummy," she said.

"Popular snacks around this time of year often have ingredients like sultanas and chocolate which are toxic to pets, but macadamias and alcohol are also dangerous and can require urgent treatment by a vet when consumed.

"Cooked bones can be just as harmful, as they can splinter and cause life-threatening internal injuries; animals will need immediate veterinary care.

"We recommend feeding your pet just before food is served or giving them a treat ball, a raw bone, or another long-lasting treat to occupy their attention and keep them away from your plate."

RSPCA Victoria animal welfare manager Nadia Peiris added that it wasn’t just food to watch out for.

"Younger animals can mistake Christmas decorations or gifts for food or toys, resulting in serious injuries from items containing glass, metal, and hard plastics that can cause significant harm," she said.

"Plants and flowers are a popular gift, and people are surprised to learn some popular plants like lilies and aloe vera are highly toxic to cats and dogs, and even can be fatal without urgent treatment.

"If giving plants as gifts, keep them on a high shelf or in another room, far away from inquisitive animals."
