Ellington woke up this morning and was really slow-moving, and he won't even jump up on the couch now. He's only 1 year old, so I know it's not arthritis or anything....
He's usually very active, and his little brother wants to play (which he usually is quick to take part in), but he just wants to sleep. He's very wobbly on his hind legs, but didn't mind when my hubby massaged them. Should I take him to the vet or wait a day?
Help!!
