ASK SONIC TO BAN THE USE OF CAGES FOR PREGNANT PIGS
In 2012, Sonic committed to phasing out gestation crates from its supply chain. The company claimed that it was working toward a crate-free supply chain by 2017, and no later than 2022. But now, the company no longer has any public commitment to eliminate gestation crates.
Imagine never being able to turn around
Sonic Drive-In is involved in one of the worst factory farming practices: locking pregnant pigs in gestation crates—cages so small that they can’t even turn around.
Since 2008, several US restaurant chains have pledged to stop using gestation crates for pregnant pigs. Eleven states and several countries have already made this practice illegal. Companies like McDonald’s, Burger King, and Chipotle have made progress, while Sonic lags behind.

What is a gestation crate?
A gestation crate is a metal pen in which pregnant pigs are kept for part or all of their pregnancies. Shortly after a pig is impregnated, the pig is moved to a gestation crate. These crates are only slightly larger than her body, measuring around 2 feet (1.6m) wide by 7 feet (2.1m) long. In these crates, a mother pig can take only a single step forward or backward and cannot fully extend her limbs. The floor beneath her is slatted, allowing excrement and urine to fall into a pit below.
EXPERTS AGREE: GESTATION CRATES MUST GO

Gestation crates for pigs are a real problem…Basically, you’re asking a sow to live in an airline seat…I think it’s something that needs to be phased out.

…[T]he close confinement of sows in stalls or tethers is one of the most extreme examples of cruelty to an animal. It continues throughout much of life and is much worse than severely beating an animal or most laboratory experiments.

Confinement of sows during pregnancy, especially in individual stalls or on tethers, can be cold, uncomfortable, and injurious, and imposes severe restrictions on natural behavior.

Negative Effects of Gestation Crates
Movement is restricted
Gestation crates are so small that a sow cannot turn around, which leads to decreased cardiovascular fitness. This restriction decreases both muscle strength and bone density, which worsens with each pregnancy. Group-housed pigs, who are slightly less restricted, show fewer abnormalities in their bone and muscle development. Crated pigs also experience more confinement-related injuries, such as pressure sores, ulcers, and abrasions. They have higher rates of calluses and limb injuries.

Injury is common
Gestation crates sit atop hard, slatted flooring, which causes foot lesions in as many as 80% of crated sows. The crate itself can also rub against the pig’s skin, causing lesions and sores. These injuries worsen as her pregnant body grows. The concrete floor causes sustained pressure on her limbs, leading to bursitis, the painful inflammation of fluid-filled sacs that provide cushion near joints. Pigs in gestation crates also suffer from a higher rate of urinary tract infections than uncrated pigs.
In natural settings, pigs choose to defecate away from their resting areas. In gestation crates, however, they must urinate and defecate in their living spaces.
undeniable stress
Crated pigs also experience higher stress levels, as shown by ACTH, A, and COR in their blood. This leads to more frequent stereotypic behaviors or repetitive behaviors that include “sham-chewing” (chewing at the air) and biting the gestation crate’s bars. Restricted movement and food intake also increases these stress behaviors. Research has also shown that pigs experience less stress in group-housed environments.
The chronic stress of confinement can also extend to piglets’ health. The stress of confinement can cause compromised immune responses in piglets born to crated mothers.
