How are 2 cats different to having 1?

[yorkypuds]

Having just had to say the saddest goodbye to our gorgeous little lady, we are thinking of getting a new cat to fill our hearts.
I would like to get two but I wondered how it works practically. Most importantly- do I need two litter trays?

My last pair were rescue brothers I got at 6 months, they lived until 17 and I miss them every single day!
They both had access to the garden so I didn’t need a litter tray until they got old and preferred to stay in.
I’m fostering an indoor cat just now and I need 2 litter trays. He can wee for the UK!
I would say for for 2 and you’ll have endless fun!
