In a "fantastic" response to this weekend's RSPCA adoption drive where every animal was adopted, the 'happy go lucky' Deisel was left behind.

Hunter regional manager Debbie Jaggers described the five-year-old staffy as a "lovable and energetic" boy with a big smile and personality to match.

According to his online profile, Deisel is searching for a family that will include him in their day to day activities, daily walks and enjoy lots of outdoor play.

But don't let his size fool you, Deisel loves nothing more than to lean in for a pat. He would love to be able to have a cosy spot of his own inside at times so he can be close to his family.

If you think Deisel could be your new canine companion, contact the shelter on 4939 1555.

Over the weekend, the RSPCA ran its Clear the Shelters which saw adoption fees slashed to just $29 for all animals.

Ms Jaggers said it was one of the best year's in the Rutherford based shelter's history.

"It was fantastic support from the community, and great outcomes for the animals. We were 99 per cent clear of our animals by Sunday afternoon," she said.

"We had more than 90 kittens, 22 cats and over 25 dogs adopted. This year, we didn't have any horses or other animals so there was a big focus on cats and dogs.

"It's an enormous credit to the shelter and hospital team."
