✅ What different vomit colors/textures can mean (and what to do)
🌿 Green with bits
Often means your cat ate grass or plant material.
What to do: Remove access to the plant and monitor. If you suspect your cat chewed a toxic plant (especially lilies/daylilies), treat it as an emergency and call a vet immediately.
💛 Yellow or green liquid
Commonly bile/stomach acid, which can happen after an empty stomach (like early morning).
What to do: If it’s one-time and your cat is otherwise normal, monitor. If it’s repeated or your cat seems “off,” schedule a vet visit—many issues can cause bile vomiting.
🧶 Clear or yellow WITH hair clumps
Usually a hairball.
What to do: Occasional hairballs can be normal. If hairballs/vomiting happen more than once a month, if your cat is gagging but not producing anything, or seems constipated/lethargic, check with your vet. (Frequent “hairballs” can actually be inflammation or other GI issues.)
🍲 Brown with undigested chunks
Often regurgitation (food coming back up undigested), sometimes from eating too fast.
What to do: Try slow-feeding (puzzle feeder, smaller meals). If it keeps happening, talk to your vet—true regurgitation can also point to esophagus/throat issues.
🤍 White, foamy
Often frothy stomach fluid (acid/bile) and can happen with an empty stomach or irritation.
What to do: If it happens once and your cat is fine, monitor. If it’s frequent, paired with diarrhea, appetite loss, or lethargy, it’s vet time.
💧 Clear liquid
Can be water + stomach fluid.
Important note: Clear vomit by itself doesn’t confirm any single disease. If vomiting is recurring, look at the whole picture (thirst, urination, weight, appetite changes) and check in with your vet.
🪱 Clear with “spaghetti-like” strands
Can be worms (roundworms are a common example).
What to do: Vet visit for proper deworming. Also clean the litter area well and wash hands—some parasites can spread to humans.
🩷 Red / pink
Bright blood or blood-tinged vomit can mean irritation or bleeding somewhere in the mouth/throat/stomach.
What to do: Urgent vet care. Don’t “wait and see.”
☕ Brown with “coffee ground” texture
Often suggests digested blood (bleeding in the stomach/upper GI).
What to do: Emergency. Go now.
🚨 Go to the ER vet (or call immediately) if:
You see red/pink blood or coffee-ground material
Vomiting is repeated in a short time or your cat can’t keep water down
Your cat is lethargic, hiding, in pain, dehydrated, or breathing oddly
You suspect toxins (plants/meds/chemicals) or a foreign object (string/yarn/ribbon)
📝 What helps your vet the most
If you can, take a photo and note:
time, frequency, color/texture, recent food/treat changes, access to plants/toys, and behavior changes (appetite, energy, litter box, thirst).
