Vomiting is a very common symptom in animals and can be caused by something going on with the GI tract or any other organ system. If the tubular structure is grass it is possible he vomited that up after eating a large amount of it or if he previously ate something and defecated it out. Sometimes pets can vomit after straining to defecate as well. One of the main concerns with vomiting in animals is foreign body obstruction, which can be an emergency. The character of that vomit is concerning. The best plan would be for him to see your vet for an exam. Bloodwork to rule out extra GI causes and xrays are likely to be recommended as the first steps. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
