If you are concerned about rabies exposure from the abandoned cat, it is essential to consult a healthcare professional or a doctor immediately.
In most cases, if you received the full course of rabies vaccination after the dog bite, you should have some level of protection against the virus for a period of time. The rabies vaccine is usually effective in preventing the development of the disease if administered correctly.
However, since rabies is a serious and potentially fatal disease, any potential exposure should be taken seriously. A healthcare professional will be able to assess your specific situation, including the details of your previous vaccinations, the nature of the contact with the abandoned cat, and the risk of rabies in your area, to determine if a booster dose or any further medical action is necessary.
Remember, it's better to be safe and seek professional medical advice rather than risking the possibility of contracting rabies, which is almost always fatal once symptoms appear.
