Poop stance and foaming in mouth

My siamese of 9 years took the 'pooping stance' in the kitchen today and his mouth started to froth. I was worried so I called him and he came over, I wiped his mouth and also picked him up, I realised there was a little bit of diarrhoea around his butt so I wiped that too. I have 3 other cats and they are all brother, so it's hard to see if he was eating properly or going to the bathroom properly. I tried to feed him his favourite cat treat and he didn't have the interest to eat it. He is usually really active but today he just sat around. Usually the first thing he does when he gets in my room is to lie on my bed, but he didn't even try to get on my bed today, he just sat beside it. He was fine yesterday, it just started today.

I really hope he doesn't have some serious sickness or something

Please help!

Thank you!

I would make a call to my vet and have him seen. With the symptoms mentioned it could be many things and only a vet will be able to give you that info.

Once you know what your cat has going on medically, there will be a lot more our community at TCS will be able help with.

Please update when you can.

Yeah I think I'll have him checked tomorrow, he's just sleeping right now. I will update after the appointment. Thank you x
