Dog and cat rivalry had been an aged old rivalry as most people knew. In fact, pet lovers were dubbed as either cat lovers or dog lovers. Not because people cannot have a cat when they have a dog, or vice versa, but because it is difficult to have both a dog and a cat for pets in one household.

However, a dog from New Zealand proved that dogs and cats can be best friends too, and in this case they can either be a life saver for either of the two.

Kim Edwards, an owner to a cat named Rory, noticed her pet limping and then collapsing immediately after. She inspected her cat and their surrounding for what could be the cause of the sudden collapse of her cat. She found out that her cat ate a poison supposedly for the cat.

Ms Edwards then rushed her cat to veterinarian Kate Heller in her clinic in Tauranga on New Zealand's north island.

Ms Heller upon quick check on Rory said that they needed immediate blood transfusion to save the cat's life. However, they were already pressed in time for a blood analysis to determine the cat's blood type and to look for donors matching the cat's blood type.

Not wanting to give up on her cat, Ms Edwards called on her friend Michele Whitmore who owned a black Labrador, Macy, and whom she knows will be more than willing to help her and her cat Rory.

Acting on purely doctor's instinct, Ms Heller conducted the blood transfusion to Rory using Macy's blood. This kind of blood transfusion from a dog to cat was never done before.

Fortunately, Ms Heller made an intelligent veterinarian's call when she decided to go on with the transfusion. Rory had survived. It may also be attributed to coincidence or miracle that Rory's blood matches with that of Macy's.

"People are going to think it sounds pretty dodgy - and it is - but hey, we've been successful and it's saved a life," Ms Heller told the New Zealand Herald.

Ms Edwards was also asked if Rory is now exhibiting some doggie habits since the blood transfusion.

"Rory is back to normal and we don't have a cat that barks or fetches the paper. The vets just went above and beyond... it's incredible that it worked," Ms Edwards said.
