£28 : Hi I think my cockatoo may have ingested some beta blocker

Birds are often smarter than to do something like this, but unfortunately we can not be sure.
For the next 12 hours I would monitor for:
- Appetite
- Breathing
- Lethargy
- Ataxia
- Falling over
- Excessive sleepiness
If you notice something abnormal in those regards, I would seek veterinary care. At this time there is not much to do except monitor, which you are likely to be the best judge at home, in his own environment,
