Feline lymphoma in 13 yr old

Hi everyone I found a large lump in the side of my 13 yr old cat
Online I could see it was likely cancer.
Vet who examined her confirm that suspicion.
He talked about the senior very deciding on the course of action.Possible biopsies blood test lump removal.Otherwise she is eating and relavitely happy now on pain relief.We had several cats and have left them a week each before deciding to PTS.
My question is has anyone had this with a senior cat.The lump is golf ball size even the vet was shocked as she went for a health check 5 weeks before.!!
My gut feeling is to euthanize than put through lots of procedures.
Thoughts anyone.

We just had our 14 year old cat PTS - vet thought lymphoma as her back legs had blown up (blood clots due to thinning). Vet agreed that lots of interventions weren’t fair on her, she’d been going downhill for ages. She was very peaceful in the end.

Sorry to hear of your cats’ diagnosis, my senior cat at the age of 10 was diagnosed with gastrointestinal large cell lymphoma, his tumour at the time was 1cm.
We decided to proceed with chemo, due to his quality of life being otherwise fine, and he lived for another 2 years.
In the last month of his life he developed a secondary type of cancer called a sarcoma, chemo wasn’t an option due to his type being resistant to chemo, we did have the option of treating him with steroids as palliative care as that is also an option, but, we decided not to, as by then his quality of life was very low (he was spending his days laying next to his litter tray and barely eating :( ) and we thought any further back and forth to the vets for him would have just stressed him out.

I think assess what your cats quality of life is, are they playing, eating etc, and also find out the treatment options with the vet and weigh up what is the best for them. Sending you love x

Oh bless you both.Vet is calling tomorrow.they thinks it's in her rib cage.She is such a lovely cat tbh.2 years I would go ahead a few months I don't think it's right although I would love another summer he did say it would be palative.I assume aggressive to grow so very quickly.🥲
Why do we love our pets so very much x

Oh no - we had this with our previous cat, our beautiful girl was only ten. Our experience was completely atypical as her only symptom was vomiting, and we’d had her back and forth to the vet several times where they were never worried as she was otherwise in rude health. She’d never lost weight, been off her food, no identifiable mass, no behavioural changes. Eventually I pushed for more tests and everything at our vet came back fine, but because we had good insurance they agreed to refer us to a specialist place where the vet cheerfully said to DP as he dropped her off that based on her scans from our vet she expected it to be a kind of cat IBS. It wasn’t.

We were offered chemo, but told the cancer was aggressive and doing that treatment would extend her life for only a short time (up to 12 months). After much to-ing and fro-ing between us, our vet and the specialist vet we opted to let her “go well” and had her pts the following week while she was still eating, happy, absolutely herself - she caught a mouse in the garden the day before.

I know some will say we went in too soon but she hated the vet and it would have been really distressing for her to be hauled back and forth. I loved her so, so much I couldn’t bear for her to suffer in any way. 🤍

Please have her PTS. Cats will often struggle to keep going and that's unfair.

whatisforteamum · 04/05/2026 19:37

Bellocchild this is my thought too.

Around February 20 this yearMy 13 year old cat Minnie had a lump on her back which turned out to be cutaneous lymphoma. The lump was removed and once she had healed, she went onto chemotherapy tablets and steroids. She seemed absolutely fine in herself until about 10 days ago when she stopped eating, started hiding and didn’t want to be cuddled.Back to the vets. She was running a fever which I thought was because the chemo had lowered her immune system. She was hospitalised during the day for three days and put on fluids and antibiotics for the infectionand I’d take a home each night. Every morning when I took her back for a checkup, they’d have to readmit her. On Friday they ran bloods again and I was told because the infection wasn’t clearing up the cancer had probably spread and that we were talking about end of life. I took her home and she died in my lap on Monday morning. I’m utterly heartbroken. I thought I was giving her the best chance, but I’ll never know if it was the cancer or the chemo that made her ill.

So sorry to hear about your cat. I know it’s easy for someone independent to say, but please have her PTS. It’s the last act of kindness we can do.

SnipItScrapBook · 13/05/2026 21:57

Sorry to hear OP. I'd choose PTS over chemo. If it's anything like human chemo then I'd avoid, due to the side effects. PTS is a kindness when a pet has a poor prognosis health wise. My old cat was PTS with lymphoma x

Vet wants to CT scan to see if lump can be removed.
After that I'm expecting her to say it's under the rib so no further treatment apart from keep her pain free.
The vet we have is very experienced and I know she will do the right thing.Sorry about your cat.
