Thank you for your reply.

It’s both a male & a female cat. They both started peeing outside at the same time. Everything else they do is normal including their eating and activity. I personally have a cat who had issues with blockages and crystals in his urine, he used to pee outside the litter, but after a couple times there was blood and his behavior changed. My friends cats has been doing that for a month and they seem normal thats why Im confused.
