We have a Siamese that is between 8 & 10 years old. He has always been VERY active. Over the last week or so, all he does is lay in one spot mostly all day. He is making it to the food/water bowls. I have not seen him in the litter box, but assume he is going. He seems to have a hard time walking and occasionally has half dragged his back half along. When he stands up, his back half kind of trembles. Should I take him to a vet or is it just old age/arthritis?
Yes, your pet needs to be seen by a vet. Good luck, vetcare
