A simple first tier weapon, a large cat will fly and explode on the ground upon impact, dealing a solid 40 damage and leaving a crater as big as a grenade would create.
You know what's more adorable that a cat? kittens. Do you know what's better? 10 kittens. The 2nd Tier of cats will make you shoot 10 small kittens in a Rapid Fire fashion. Depending on the distance they can deal 5 to 12 damage. Due to their smaller size, the kittens all have a smaller blast radius when compared to Cat.
Is it a bird? Is it a plane? No, its Super Cat! The third tier that require 3,100xp resembles the first tier mentioned earlier, but more powerful. It deals 55 damage and has a bigger blast radius. True to its name, it is also seen wearing a red cape.
Unlike the previous variants, Cats and Dogs shoots a flare, rather than a direct impact shot. If you're wondering why the flare is a dog bone, that is because there are dogs in this tier. Soon after the flare lands, it literally starts raining cats and dogs. The damage and blast radius varies depending on the size of the animal that hit the enemy.
Cats and Dogs was formerly the highest damage weapon in the game, it used to deal 16x22, firing enormous 32U projectiles. When the game moved to steam, this weapon was nerfed so excessively, that most high level players refuse to use the weapon.
The number of cats and dogs is completely random, sometimes resulting in a rare occurrence where only one animal is rained down with the other animal entirely absent from the weapon's effect.
Similar to Synclets and Needler, Kitten's spread is caused by the shots having a varied power.
