How long does it take for amoxicillin to start working on cats?

Typically, amoxicillin starts to take effect within 24 to 48 hours after administering it to your feline friend. However, it’s crucial to keep in mind that the cat’s body needs time to absorb the medication, so it might take a bit longer for the full effects to kick in.
