He hasn't had a poo since last Thursday. He's hiding under the bed and won't come out. I've taken the litter tray to him and tried to put him in it - he did a massive wee but that's all. He won't come down to eat so I've been taking up little bits of tuna and a couple of dreamies which he's eating. He won't drink water but will have a couple of licks of lactofree milk. Took him to the vet yesterday- temp is high 39.1 but all bloods completely normal. No faeces felt in colon and good anal contraction. Taking him back in the morning for a possible ultrasound but any ideas? He's 7.
