Hello Erin…..you need to take him to the Vet. Urinating suddenly like this could be sign there something wrong…kidneys, crystals a bladder infection…all sorts of things. Take a urine sample with you if you possibly can, it will help the Vet pinpoint the problem.
Hope he recovers soon!
Aleshia that sounds awful – I am so sorry to hear this. Could you take her to the emergency vet tonight?
