Help I have a 8months yrs maincoon at 5.70lb

[Willmath]

Last friday i made my dream come true, having a maincoon, but the issue,he is 8month look like a 4months, weight 5.7Lb skin/bones, my girlfriend said he is suppose to be 15lb at that same age. He is having hardtime eating. The previous owner tried a lot of ways. But he doesmt seems to gain any mass. He has no energy sleep most of the day. The previous owner will take him back, but Tomorrow might be His last day.
Should I let go, are you think there is a way.

Please what do you think

I think there is almost definitely something medical going on and he needs to see a vet yesterday (immediately, that is). You could save his life.

he has seen a vet at 4months for fluid and antibiotics, but no echo was done. The breader agreed to take the kitten back since it was only a "test week". But started to talk about Euta in the message.

What was the vet's diagnosis? Did the vet do bloodwork, e.g. CBC? Have you considered getting a second opinion from another vet?
You mentioned he is having a hard time eating, did anyone check his mouth or teeth?

I hope you are able to find out what is ailing your cat so that you can get the proper medical treatment for him. Best of luck!

This kitten has something serious going on, and either the breeder or the vet is very remiss with diagnostics and/or treatment. I cannot tell you what to do, only that you have to follow your heart. SHOULD you keep this kitten, take him immediately to a vet that YOU have chosen. You may be his only chance.

Agree totally re vet ASAP. Cannot believe anyone rehomed a kitten in this condition without a full vet check

If he hasn't seen a vet in 4 months of this going on, I don't think all (or any) possibilities have been exhausted. Euthanising him would surely be a last resort, not the first response to a kitten who isn't eating/gaining weight?
I agree with the others. The breeder seems like the kind of person who shouldn't be taking care of cats (or anything for that matter), let alone breeding.
You may truly be his only chance at this point.

Get a simple x-ray and see what is going in inside. They are not that expensive. That poor little guy needs medical help right away. a kitten that doesn't eat has something very wrong, and it may have a simple fix.
