The four-year-old pot-bellied pig, who is named Dad Pig, has been cared for at a farm in North Warnborough, Hampshire since his owner died.
Now the search is on for someone who can provide him with a permanent home with the company he needs.
The RSPCA encourages anyone who is thinking of rehoming a rescue pig to thoroughly research what is needed to meet the welfare and legal requirements.
Contrary to popular belief pigs should not eat kitchen scraps, it is illegal in order to prevent the risk of disease.
They need to eat a commercially prepared pig feed which contains the correct balance of protein, vitamins and minerals.
They can drink up to 20 litres of water a day and need regular health checks. They are social animals so need company and also need regular exercise and plenty of stimulation.
Pig owners also need licences to move and certificates to exercise their animals.
