I have a 1 1/2 year old cat....The last few days I've noticed he goes to the litterbox at least 5 times in an hour...But he has trouble using the restroom...Last night he jumped on my blankets and he pee on it but I don't think he meant to do it...His pee was a reddish color...He always sleeps on my bed at night but now he sleeps beside the bed...I don't know if its something he ate or if its because I just recently change the brand of litter...But my other cat is fine...If anyone knows anything thats could help him, please let me know
