Ouch! Your cat can also have a reaction to a bee sting. The first thing you may notice is swelling in the face or muzzle, and even large lumps or bumps all over the body. If you notice any of these symptoms please contact us immediately for medical assistance. Remember, a bee stinger can release venom for up to three minutes after the bee leaves it in your pet’s skin so try to remove the stinger as soon as possible.
