RSPCA workers are caring for a young piglet which was discovered in a lorry-load of toilet paper.
The RSPCA said those responsible had been thoughtless
The animal, thought to be two to three weeks old, was found among a delivery at Tesco in Ilkeston, Derbyshire.
Staff said they were unsure of how the piglet, nicknamed "Andrex", came to be on the lorry but believed it might have been a deliberate prank.
The piglet suffered cuts and bruising to his snout and will be rehomed when he has recovered.
Ella Herring, deputy manager for the Radcliffe-on-Trent animal shelter, said: "If this was a deliberate prank, those involved have spared no thought for the animal's welfare.
"Fortunately Tesco staff acted quickly in contacting us and kept the piglet warm until the RSPCA arrived.
"We will now care for him until he is fit enough to be found a permanent home."
A Tesco spokesperson said: "Staff are used to dealing with the unexpected, but little Andrex's arrival was a shock.
"They took it in their stride, wrapping him up straightaway in a duvet in the manager's office and calling the RSPCA for advice and help.
"It was distressing for everybody to see the piglet in such a sorry state."
