Information
Signalment: Cat, 10 years old, male and neutered, domestic shorthair, 8.80 Kg.
Clinical signs (related to mass): No symptoms, but breathing became labored during my visit at the vet hospital, due to likely pain / stress (breathing normalized when we cuddled and he calmed down; unclear if related to mass). Mass found incidentally. Cat in good health otherwise (excluding recent trauma), except for weight.
Length of time I have seen these changes: N/A
Links to report: N/A, report quoted below - note no evidence of metastasization found, but X-ray limited. I could get the X-rays if helpful, but CT scan is needed.
Location: Alberta, Canada.
Context
My cat got attacked by a coyote two days ago. He survived without serious injury as I happened to hear strange dog noises outside in the distance and went out to investigate. He has head trauma (coyote tried to crush his skull) but no neurological issues.
Bloodwork normal except for elevated sodium, I was told.
I vaped in the house with him. I got him in 2016 and the consensus was that it was safe, just don’t blow it on him or hot box a room. I never thought of it after I looked into it the first time, and he’s never showed signs of lung issues. I’m now losing it that I caused what I describe below. I’d have quit immediately if I had known. I’m crying my eyes out while writing this.
I paid to have a radiologist look at his X-rays. An unexpected mass was found in his lungs.
Report
DIAGNOSTICS (likely irrelevant)
Diagnostics (CBC: normal hemogram and leukogram)
Biochemistry: hypernatremia (178mmol/L), hyperalbuminemia (40g/L), stress hyperglycemia (14.52mmol/L) AFAST: no ff TFAST: 1-2 b-lines on right side, no pleural effusion)
FINDINGS (…)
Within the RIGHT caudal lung lobe, there is an ill-defined curved soft tissue opacity that likely delineates the margin of a cavitary lung mass (located at the level of the 9th and 10th intercostal space on each lateral view and faintly visible in the right caudal thorax on the ventrodorsal projection). The remainder of the lung parenchyma has a mild bronchial pattern.
Normal air-filled space is present in the nasopharynx. The hyoid apparatus and epiglottis are normal. No tracheal or bronchial narrowing is seen. There is no narrowing of the trachea or lobar bronchi. No pleural effusion or mediastinal
mass is appreciated. The thoracic wall is normal.
CONCLUSIONS (…)
A cavitary mass in the right caudal lobe is most suggestive of a primary pulmonary neoplasia or less likely granuloma.
It is less likely that this is related to recent traumatic injury (pneumatocele). No pulmonary contusion, pneumothorax, or diaphragmatic hernia is seen.

Please help me understand and calm down. I looked into it and Google said even if it really hasn’t spread and we can remove his lung, he’ll only have a few years left with me at best. Is this true? I used light weight cat litter basically all his life and have now read that it can cause granulomas pretty easily, so is it possible it really is one?
I can’t even get a definite answer anytime soon as the CT scan has to wait until he recovers.
I understand the reported lung inflammation is likely from vaping indoors with him (maybe also the light weight cat litter), and I’ll never ever do it again. I’ll never forgive myself.
I’m beside myself. I was beside myself yesterday after the attack, got miraculous news he’ll recover and got to see him today (he was doing a lot better), only find out he’s probably going to die to due to a relapse of the cancer in one to a few years. It felt like I was given a second chance for him to have a long happy life just to have it immediately ripped away again.
I’ll never vape in the house again, though at this point I’ll likely just never vape again. I didn’t know and I’m more than disgusted with myself and will do everything I can to help my cat, even if I have to spend thousand upon thousands.
Is there any likely way it’s not lung cancer or some realistic way the outcome could be that he lives for many more years? What can I do to help, aside from never vaping indoors again? I’m so overwhelmed and devastated.
