Conversely, I fostered a 2 year old dog, Gizmo, who raised a 4 week old kitten, Jethro, my son rescued. They were so tight, Gizmo would toss Jethro around like a rag doll. Jethro would come back for more! Gizmo was known to carry Jethro around the house by his head in her mouth.

We found a forever home for Gizmo almost 2 years ago. Jethro still sleeps on Gizmo's spot on the couch.

Gizmo now lives with 1 grumpy old cat who gives her wide berth, 3 sibling cats, their mom, and a kitten. She gets along fantastic with all but the old one.

I have no idea what Gizmo's life as a puppy was like, but when I rescued her at about 2 she was pregnant (likely with coyote pups), had been poisoned (unsure if intentionally or from her eating rodents who had been poisoned), was anemic, and had canine ehrlichia. I found her abandoned at the Rio Grande near where I walk Furiosa.

I think raising a cat and dog together is going to improve their chances of getting along, but not assure it.
