My cat is scratching at the collar, causing redness and irritation. What should I do?

There is a slim chance that your cat might develop mild reactions such as scratching, redness and hair loss. These symptoms usually disappear within one to two weeks, without removing the collar, as your cat gets used to wearing it. In some cases, temporary collar removal may be recommended until the symptoms have disappeared. In very rare cases in cats, application site reactions such as dermatitis, inflammation, eczema or lesions may occur and in these instances, collar removal is recommended. Please consult your vet if the symptoms persist or become more sever.
