Cats moved house- not happy!!

[AMF88]

Hey all I moved house over the weekend, I took my two cats last when the new place was relatively organised and calm so there wasn't lots of noise and people. One of my cats, the oldest of the two at 4yrs, seems ok, he is tentatively walking from room to room providing someone is close. The other cat, he is 2yrs old, is so sad, he is hiding underneath the sink, I don't think he has eaten or used litter tray in 24hrs and if you try to grab him he will cry and back away.
Any advice? It's starting to upset me now because he is such a loving adverturous cat, and he just seems so scared. Does this last long? Will he just get used to it and reappear?

He'll get used to it but how long it takes is anyone's guess.

Don't let them outside for a month & make sure you update their microchip details.

Ok thank you.
They have never been outside because we live in inner city and up until now we have lived on top floor flats with limited or no outdoor space. We now have a garden so did intend to let them out once settled.
Hopefully when I get home from work he has emerged from his hiding spot!

We moved last year and our cat hid in our bed for a week. Came out for food and water and then just went back in.

Very odd behavior from her - she never tries to get in bed normally.

Then she just stopped and returned to normal

Give him time....
