Pets suffer from secondhand smoke

As you know smoking is bad for you, but it is bad for your pets too. Pets breathe in  smoke and sometimes they eat  cigarette or cigar butts which contains thousands of toxins. Sometimes they  drink water that contains cigarette butts, so they are swallowing a toxic soup of chemicals. Animals also groom themselves by licking and they swallow the toxins that have settled on their fur through secondhand smoke.
Just like humans you pet's health is affected by secondhand smoke. Asthma, heart troulble, lung issues and potential death could be avoided if your pet was not exposed to seconhand smoke.
