Customer Question

I spoke to Dr B yesterday about my 11 year old. I just realized he ate some chopped onions in leftover tuna salad on Friday. He's still listless. Anything I should do?

Oh dear,

How much onion was in the tuna?

Are his gums pink or pale/white?

Any drooling, gagging, or vomiting?

Customer: replied 10 months ago.
I`m not sure; it was premade. Gums have some white tinges, but no more than yesterday.. No drooling or gagging.
Expert:  Dr. B. replied 10 months ago.

No worries,

Now as long as those gums stay the color they've been, we can monitor that. The reason I asked about those signs is because onion in cats usually causes lethargy, GI upset (vomiting or appetite loss) but in high doses can also cause anemia (often days later though) In light of this additional history, I'd advise again to use those antacids we discussed (Pepcid (More Info/Dose @, or Tagamet (More Info/Dose Here @ to soothe his stomach. Then we'd want to see if we can get him eating. If he settles, we are happy and can monitor his gums for anemia signs (paling) over the week. But if he doesn't settle or we see paling, then we'd want him seen by the local vet for symptomatic care to counter this exposure that is likely what has triggered his malaise and feeling unwell.

Kind regards,

Dr. B.

Thanks for your advice. I`ll monitor him and give him some antacid, and get him seen to tomorrow.
