Story
Our cat's name is Leo and is 8 years old. He has had issues with one of our other cats for about 4 years ago to the point where we have to keep her separated. Recently he injured one of our other cats and our house hold is no longer safe for either of them. He is a very sweet and loving cat, but has developed behavioral issues with other cats over the years. We have had him since he was 6 months old. He also has special needs, where he is on a strict diet, 3 to 3.5 ounces of pate wet food morning and evening. He had diabetes and almost lost his life to it, but luckily my wife and I were able nurse him back to good health and his diabetes is in remission. We take him in for his yearly check up to make sure he is still healthy. He also chooses when he wants to poop in the liter box or next to the liter box, but that may be due to 3 other cats using both of our extra large liter boxes.

Story
Our cat's name is Grimm and is 8 years old. Over the years he has become aggressive towards two of our other cats. We have his liter mate Leo who has also become aggressive towards our other two cats. He had a large bladder stone a few years ago that was life threatening and had to be surgically removed. He is really loving cat and loves to cuddle, play, and be glued to your side.

I'm River, and I'm the kind of girl who likes to take it easy. Chilling on the couch, basking in a windowsill--why not live the mellow life? Let's live together and watch TV. My favorite show is Paw Patrol!

Hi, I'm Mona, and I'm an introvert looking for a fellow-introvert to spend quiet evenings on the couch with. I like the finer things in life like a warm blanket and some gentle petting.
