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.

Members of the public are still urged to stay away from University Hospital Llandough following an outbreak of the winter vomiting bug Norovirus.
Cardiff and Vale University Health Board, which first issued the warning on Saturday, said precautions will continue over the next few weeks in a bid to contain the spread.
Cardiff and Vale University Health Board is recommending people stay away from Llandough Hospital following an outbreak of norovirus.
Norovirus is an extremely common bug, which is not normally dangerous.
Cardiff and Vale University Health Board has warned that "the effects can be more serious" for ill and vulnerable patients.
Many people will have the norovirus bug at this time of year – we see it every year and, for most people, it will be unpleasant but not serious.
But when norovirus spreads in hospitals, where patients are already unwell and are in close proximity to each other on wards, the effects can be more serious.
At this stage, we’re asking people to be sensible and to stay away from the hospital if they possibly can, to avoid spreading the bug.
It may be that you’ve had norovirus yourself and are feeling a bit better and think it’s safe to come in and visit. The reality is that there needs to have been at least 48 hours since your symptoms cleared before you can be confident that you’re not going to spread the bug to someone else.
We know that it’s difficult when people have friends and relatives in hospital. Over the coming weeks, we’re asking for the public’s help in helping us to limit the spread of norovirus so that we can protect vulnerable patients from the effects of this nasty bug by staying away from the hospital.
Visitors have been asked not to go to University Hospital Llandough in Penarth unless absolutely necessary over the next few weeks, after an outbreak of norovirus.
Cardiff and Vale University Health Board says the so-called winter vomiting bug is affecting a number of patients on two wards at the hospital.
