I have had cats for 18years, from kittens to elderly. I have alot of experience with medications for cats for different ailments. I have also volunteered for a cat rescue and dealt with trapping feral cats for a neuter programme. I have never owned a dog myself but i have been around them alot. My neighbour used to have a very boisterous staffy cross, she was very big but she was good on a walk (mostly!) I have been around plenty of small dogs too.
