Yes.
Probably less of them than under Trump but there were kids in cages and kids separated from their families under Obama.
Those photos of immigrant children “caged” by the US? They’re from 2014

"Immigrant girls sleep in a cell, Jun. 18, 2014."
Also, here's a pbs article from 2016 with the same image:

Update, June 18: Since this story was published, new photos have been released by the US Customs and Border Protection, revealing current detainment conditions for immigrants apprehended at the border. The current conditions closely resemble the Obama-era “cages” depicted in photos from 2014. In both cases, children are shown separated from their families, sleeping on the floor within steel-wire enclosures.

In 2014, the Mexican American Legal Defense and Educational Fund filed a complaint reporting widespread allegations of sexual harassment at the Karnes County Residential Center, also in Texas, where more than 500 women were detained with their children.

To address a point that came up in the comments.
Were illegal immigrants without criminal records for anything else arrested under obama:
Over the first full 14 months of the Trump administration, 69% of undocumented immigrants arrested by Immigration and Customs Enforcement (ICE) agents had a criminal record. Over the final two years of the Obama administration, that number was 86%.
ICE agents have arrested an average of 4,143 undocumented immigrants without a criminal record each month under the Trump administration. In the final two years under Obama, the agents averaged 1,703 a month.
Those numbers show the radical change in immigration enforcement implemented by President Trump, who issued new directives to ICE shortly after taking office in January 2017.
ICE arresting more non-criminal undocumented immigrants
So 14% of immigrants arrested by Immigration and Customs Enforcement under Obama didn't have a criminal record other than that related to immigrating illegally.
