The weight gain is somewhat of a vague sign, but I am worried when I hear of a cat "wheezing", as it suggests feline asthma, which is a fairly common malady and often presents itself as you are describing. I would consider this to be a fairly urgent matter and would get her into the vet for a thorough physical exam and chest x-rays as soon as possible; asthma can cause serious breathing compromise if not diagnosed and treated.

    Wheezing and gasping for breath are certainly not "normal" findings, even if they only occur during times of stress or excitement. Definitely mention this to Felix's vet again because this could indicate the presence of feline asthma. Chest x-rays are not a definitive test for asthma, but are likely to raise or lower the suspicion of this condition. Always trust your gut when it comes to your pets' health!

    I am sorry to hear about Lucy! If she is wheezing and taking very shallow breaths, this is not normal. It could be allergy related and we can see asthma in cats. We also worry about heart disease in cats who have breathing issues. We also can see breathing issues with heartworm infection or lungworm infection. I would recommend a visit to your vet along with x-rays of the chest to check the heart and lungs for signs of these diseases. Depending on what they find, appropriate medication can then be started to try to help her be more comfortable!
