You should only give your cat asthma medicine if it has been prescribed by your vet. Asthma medication for cats, such as bronchodilators and corticosteroids, should be given in the correct dose and frequency as instructed by your vet.
It is essential to never give your cat any medication intended for humans without consulting your vet first. Some human asthma medications or remedies can be toxic to cats or have serious side effects.
If you suspect that your cat has asthma or is having difficulty breathing, it is important to take them to the vet as soon as possible for diagnosis and treatment. Your vet will be able to prescribe the appropriate medication and dosage for your cat's specific condition.
