Fourteen geckos have been found dumped among communal bins in Penarth.
The lizards were discovered inside four plastic boxes by a local resident who was using the bins at Park View Court on Sunday.
The RSPCA says there was no food or water inside the boxes but the geckos were in good condition and were transferred to a local wildlife centre.
RSPCA Inspector Gary Lucas said, "We are trying to find out where these lizards came from and how they came to end up among these bins.
“It is unusual because there was such a large number of them which makes it more likely that someone will have information about where they came from."
Anyone with information is asked to call the RSPCA inspector information line on 0300 123 8018.
The owner of a dog found travelling alone on a train in Swansea is being sought by staff at RSPCA Cymru.
The sandy-coloured Chihuahua was discovered in a carry case by a guard on the Arriva Trains service from Manchester Piccadilly to Carmarthen yesterday afternoon.
RSPCA workers believe the dog to be elderly, but otherwise healthy.
Inspector Nic De Celis said: “There could be someone out there who is missing this dog and is frantic with worry and we’d really like to reunite them with their pet. But at the moment the reason why this dog was left alone on the train is a complete mystery.
“We are keen to speak to anyone who has any information, whether they noticed the dog while travelling on the train or if they know of someone who is missing a Chihuahua”.

An orphaned otter cub is making good progress at an RSPCA wildlife centre, after being rescued from the bank of an estuary in Gwynedd.
A member of the public heard loud squeaking noises while out walking near the village of Talsarnau on Boxing Day and found the young cub on the bank.
The RSPCA says the cub was becoming increasingly distressed and as there was no sign of his parents returning, he was taken into the care of a local vet. He's now being cared for at the RSPCA Stapeley Grange Wildlife Centre in Cheshire.
Rob Scrivens, otter rehabilitation co-ordinator at Stapeley, said: "This youngster is around 9-10 weeks old and is a really feisty character, which is very good sign. He is currently eating well and seems bright and healthy.
"It is unclear why he was separated from his parents but the recent bad weather could be to blame."He added that once the cub is big and independent enough to fend for himself he will be released back to the wild.
RSPCA inspector Mark Roberts said: "This little otter has somehow become separated from his mother and could have died without intervention.
"We would like to remind people before touching any baby wild animal, we always advise monitoring first to check that it is genuinely orphaned or abandoned, as mum is often nearby and waiting for you to leave."
RSPCA Cymru is welcoming the Welsh Government’s plans aimed at tackling fly-grazing and abandoned horses and ponies.
The Minister for Natural Resources and Food, Alun Davies AM, yesterday announced his intention to fast-track the Control of Horses (Wales) Bill through the National Assembly for Wales.
The Bill will give local authorities the power to seize, impound and make arrangements for horses found fly-grazing or abandoned on public or private land without permission.
Owners will be given seven days to come forward and will also be liable for costs incurred by the local authority over that time.
Efforts are continuing to rescue ducks caught in an oil spill at a pond in Denbighshire. RSPCA officers were called to Glyndyfrdwy, Corwen yesterday after reports oil was dumped in a pond there last week. Around 200 ducks have been rounded up and taken to an RSPCA centre in Somerset for cleaning.
RSCPA Inspector Keith Hogben said: "There is no doubt that this oil was deliberately dumped and these poor birds have been suffering as a result. If we were not wading in to the rescue they would be unlikely to survive."
Around 180 ducks have been rescued in Denbighshire, after oil was poured into a pond. The RSPCA says they believe the pond was deliberately polluted as it is in a remote location in Glyndyfrdwy, Corwen.
Between 300 and 400 birds are believed to be affected by the incident.
The RSPCA in Swansea says it is seeing an increase in the number of abandoned cats and kittens it's taking in.
Staff there described this year as the 'worst ever' for the problem and said they're struggling to cope.
The problem stems from cat owners being caught out when their un-neutered pets have litters.
Now the society is working with Cardiff University to try to establish why owners aren't taking preventative measures.
A St Bernard dog weighing 12 stone has been rescued through a window after its owners were suspected of abandoning it at a house in Mountain Ash.
It took three officers, two members of the public and a police inspector to remove the dog from the property, where he was discovered along with a cat and a hamster.
The three animals, said to be in a 'reasonable condition', are now being cared for by the RSPCA and will be rehomed in 14 days if the owners do not come forward.
Anyone with information is asked to contact the RSCA on 0300 1234 999.
The RSPCA says it is being swamped with abandoned kittens at its branch in Swansea, with staff saying its the worst year ever.
Now the organisation is working with Cardiff University to find out why owners aren't getting their cats neutered.
A cygnet has been put down after its leg was broken in an apparent stone throwing attack yesterday says the RSPCA.
A member of the public called the charity after witnessing what she claimed were two boys throwing stones at the cygnet and two adult swans as they swam on the river Ogmore.
One of the stones directly hit the cygnet and the witness described how the adult birds tried in vain to get it out of the water but it kept falling over as its leg appeared to be broken.
When RSPCA inspector Keith Hogben arrived at the scene at Merthyr Mawr near Bridgend he picked up the cygnet and took it to a local vet who confirmed that the cygnet’s femur was smashed. The bird was put it to sleep as a result.
Inspector Hogben said, “I am disgusted by this attack on a young, defenceless swan. The poor animal didn’t stand a chance. "
Anyone with information about the incident can contact the RSPCA 24-hour cruelty line on 0300 1234 999.
